     The purpose of this catalogue is to help revive classical microbiology - a subject that should never have been treated as a specialty subject but as a subject, which must be known and understood by everyone.

     Microbiology is an exciting way of introducing students to science. It is also a way of orienting students towards a variety of careers. Medical and para-medical professions are the obvious ones but microbiology is also essential for environmental sciences such as water quality and waste management, pollution studies and abatement, management of toxic wastes, and agriculture, especially alternate methods of farming based on natural versus chemical farming. Microbiology is also essential for biotechnology, genetic engineering, fermentation, food and pharmaceutical industries, and space exploration.

     Microbiology is also essential for understanding the economy of nature and the balanced way in which nature functions. As such it has direct application in the areas of economics and in developing sound economic institutions and policies - an application hitherto unexplored. This aspect of microbiology is especially useful now when we need to design interdependent, perpetual, productive and efficient economic systems, which could not only sustain but also aid in improving the quality of life of expanding human population.

     There is no better place to learn and see principles of such systems in operation than in microbiology where an organism divides into two before it becomes inefficient, where small is sustaining, not only itself but the rest of the pyramid of life upto its very peak. It is this knowledge, which must go into the making of our economists, philosophers, and thinkers. Unfortunately, economic majors neither necessarily study biology nor microbiology. How can we expect them to create viable economic systems if we never exposed them to the only known perpetuating system which has existed from the beginning of time and which still goes on despite all the follies of humankind. A revival of classical microbiology with its philosophical implications should thus be a priority for teachers, administrators and planners and they should see to it that this knowledge becomes part of everyone's general knowledge.

     Microbiology is also essential for personal hygiene and disease prevention. It was the knowledge of microbiology that, upon reaching the public via newspapers, enhanced standards of living and brought infectious diseases under control. Only when we took this knowledge out of public awareness that the diseases began to surface again. The public fought polio more than the established government and academic institutions. Same can be done for Aids but for that, teaching of classical microbiology has to be revived and it should, once again, be made part of everyone's knowingness.

     Too many colleges and universities are now giving microbiology the back seat. In many cases, even though the departments are named "Microbiology," their course offerings and the thrust of their educational direction is no way near the classical discipline of microbiology. This, infact is a disservice for the public and even the planners at the national and international level keep on believing that microbiology is alive and well. The reality surfaces only when they need a microbiologist and learn that the one who carried the credentials was not a functioning microbiologist.

     This trend needs to be changed which is partly due to funding priorities forcing microbiologists to branch out into other areas yet continue to wear their original hats. Unfortunately, as time goes on, their newfound interests begin to shape their course contents at the expense of classical microbiology. Their students in turn reflect their own interests in the courses they offer, making each successive generation farther and farther removed from classical microbiology.

     This shift in funding priorities, coupled with lack of appreciating the importance of classical microbiology, led many institutions, in the 70's, to make microbiology a lecture and demonstration course while to know this subject well, one needs to go through a hands-on curriculum which is lab based. No one can fully grasp the impact of microbiology unless they have seen living microorganisms under a phase contrast microscope. That is one of the reasons why Zernick was given the Nobel prize in 1935 for inventing this microscope. How many educational institutions are using this educational tool to open up the world of microorganisms to their students? You may be thinking that this will be an expensive proposition but in reality it is not so, especially when phase microscopes are not as expensive now as they once used to be and also when all one needs is one phase microscope per class and even that can be shared with other classes. The fact is that curriculum designers of today are not familiar with the educational value of such tools. This again casts a poor reflection on the educational institutions and their faculty who failed to appreciate the importance of their basic discipline and thereby failed to ensure its perpetuity. The damage in this area is far too severe which can be easily assessed by realizing that there exist, in this nation of ours, professional schools where microbiology is no longer taught to students of nursing and to students of pharmacy. Need I say more. That is why we have to revive classical microbiology and we have to do it now.

     The best way to revive classical microbiology is to facilitate hands-on lab-based teaching of microbiology. Here, the most common compliant is that the essential materials and supplies are either too expensive or are not available. Most lab., supply houses, which once used to cater to schools and colleges, are now concentrating on supplying to hospitals, clinical laboratories, industries and research institutions mainly because that is where the money is.

     Under these circumstances, the way to revive classical microbiology is to make available needed microbiological supplies and also to provide any guidance the institutions and the instructors may need for teaching this subject. It is for this reason that this mini-catalogue of microbiological supplies was put together. It contains only the essentials needed to teach a hands-on lab-based course in microbiology and to do so inexpensively. The supplies contained in this catalogue are designed for classroom use only and are not intended for clinical or other testing laboratories or for research.

     This catalogue provides you everything that you need to teach a good "hands on" course in microbiology in one place. Nothing extra to hunt for or to buy. By using this catalogue you can teach your students a comprehensive course in microbiology covering such topics as:
  • An introduction to the ten major groups of microorganisms.
  • Sampling techniques and the isolation and cultivation of microorganisms.
  • Pure culture techniques in microbiology.
  • Cytological, biochemical and serological procedures.
  • Identification and quantitation of microorganisms.
  • Immunological procedures.
  • Microbial genetics.
  • Industrial microbiology procedures.
  • Sanitary and environmental microbiology procedures.
  • Clinical microbiology procedures.
  • Mycological procedures
  • Virological procedures - propagation and quantitation of viruses.
     All items included in this catalogue are GUARANTEED CLASS ROOM QUALITY MATERIALS and are provided in standardized form in sufficient quantities to suffice for a class of up to 30 students.
     A COMPLETE OBJECTIVE ORIENTED LABORATORY MANUAL covering the entire basic and applied field of microbiology is also available (see details on page 31 of this catalogue). This manual together with this catalogue is an ideal combination for you to update your microbiology courses and to make them exciting learning experiences for your students.
     The use of the manual, however, is not mandatory, for the catalogue will compliment any laboratory manual that you may now be using or wish to use.
     Please also note that since we specialize in providing only microbiological and immunological supplies through this catalogue, we can assure you prompt deliveries with almost no back orders. You will also like our low prices and when you call us you will find a knowledgeable person on the other end who can not only answer your questions but can also consult with you intelligently.

     The vastness of microbiology can be overwhelming to a student especially when we, as teachers, emphasize that microorganisms constitute a large group of diverse organisms. A beginning student is not able to relate to such a generalized statement. He wishes to have a sense of reference and a way to relate to the vast number of organisms.      One of the ways to give such a sense of reference is to introduce the students to the major groups of microorganisms. Generally, microorganisms are placed in anywhere from 10 to 12 major groups. These are: algae, protozoa, fungi, actinomycetes, blue green algae, bacteria, mycoplasma, L forms, Rickettsia, Chlamydia, slime molds, and viruses. Kits listed below provide related live and/or preserved materials to introduce students to all of the above groups of microorganism. With the help of these materials you will be able to show the students actual organisms and/or their colonies rather than just talk about them. As we all know, there is no substitute for learning by seeing and doing.


     This material is supplied in a kit form and includes selected live and/or preserved material for introducing students to algae, protozoa, slime molds and fungi. Material is sufficient for a class of up to 30 students.

     Catalogue # HP-1 Higher Protista Kit   $75.00

     While there is an overwhelming number of cultures, one needs only a few, in most cases nonpathogenic ones, to teach the essential principles of microbiology. Nonetheless, the list on the following pages is rather extensive and is provided so that different instructors can select cultures of their choice.

     We would, however, like to emphasize that keeping too many unnecessary cultures in a teaching laboratory is time consuming as they need to be transferred frequently and also their purity has to be tested at frequent intervals. This time can be saved by keeping only the essential cultures and limiting one's stock of cultures to the hardier ones rather than those which die rapidly when maintained in the laboratory.

     It should also be noted that live cultures are not always necessary for teaching principles of microbiology. Procedures designed to demonstrate morphology and staining reactions such as the Gram stain and cytological stains can be performed on killed cultures. Live cultures are essential only for biochemical reactions and for growth experiments. Immunological and serological reactions also do not require live cultures. Killed cultures are the cultures of choice here, and this catalogue provides such cultures. These are easy to keep and since they have a longer shelf life, they are economical to use. A considerable amount of cost can thus be saved by using the killed cultures as opposed to live cultures.

     The use of the killed cultures also enables the students and staff to be less apprehensive about working with microbes, especially since the connotation "germs" is associated with disease production. Such cultures would, therefore, enable you to add lab based microbiology courses at introductory college or even at high school level. We take used equipment as trade in. Write or call for details.

VL-01 ------- Escherichia coli T4 phage (use E. coli strain B for propagation)


     While you can prepare your own media, a considerable amount of cost and time can be saved by purchasing prepared media provided you limit the purchase of such media to what is actually needed. Even if you prepare your own media, do not prepare more than what is needed. Microbiological media, especially agar plates, have poor shelf life as they not only dry out but also tend to get contaminated with repeated handling.

     For these reasons, this catalogue lists only those media which are essential for teaching a comprehensive course in microbiology. Prepared media are supplied, sterile, in tubes as slants, deeps, and broths and in standard size Petri plates as agar plates.

     Certain media to be used as plates are also bulk packed in two size bottles. One size bottle has sufficient amount of the medium for preparing 15 plates. The other size has sufficient medium to prepare 5 plates. These bulk packs are specially useful for doing viable counts.

     This is an economical way for preparing plates as the bulk packed medium can be melted and poured in plates as needed. If the entire contents of the bottle are not used, the leftover medium can still be saved and re-melted for preparing more plates. While such re-melted medium may not be suitable for performing clinical or other tests, it is perfectly acceptable for teaching purposes.

     Occasionally also, when only a few plates are needed, agar medium supplied as deeps can be melted and poured into plates. For this reason each deep, as supplied, contains sufficient medium to pour one plate.

     Size and description of containers of prepared media

     All broth tubes are supplied as 16 x 100 or 16 x 150 mm screw cap tubes.

     All slants are supplied as 16 x 100 or 16 x 150 mm screw cap tubes.

     All deeps are supplied as 20 x 150 mm screw cap tubes. Deeps contain approximately 18 ml of medium which is sufficient to pour one plate.

     All stab media are solid or semisolid agars. They are supplied in 16 x 100 or 16 x 150 mm screw cap tubes.

     All bulk packed medium is supplied in approximately 250 ml quantity in 500 ml screw capped bottles or in approximately 100 ml quantity in 250 ml screw capped bottles. Melt media in these bottles by immersing them, halfway, in a beaker of water and then bringing the water slowly to a boil. Keep boiling until the medium is fully melted. Cool medium to approximately 45 C and then pour plates.

     This bulk packed solid medium is also useful for doing viable counts. For this purpose, medium packed in 100 ml quantities is preferred as this amount is sufficient to pour 5 plates.


     The following media are supplied sterile in screw cap tubes, bottles, or Petri plates. Minimum order is 10 tubes or plates. Order additional media in increments of 10 also. No minimum order on botttled media. Media marked with an * are special order media at $1.50 each. All other media are priced as follows:

     Regular broth tube or agar slant is $0.60 ea.
     Blood or chocolate agar slant is $1.25 ea..
     Agar deep is $0.75 ea.
     Broth tube with gas vial is $1.25 ea.
     Agar plate is $0.65 ea.
     Agar bottle containing 250 ml of medium is $15.00 ea.
     Agar bottle containing 100 ml of medium is $10.00 ea.
     NOTE: The institute assumes no responsibility for breakage of bottles or tubes while melting agar media contained in them.

      The purpose of this test, in an educational setting, is to demonstrate to the student why this test is necessary and how the test is performed.  In order to impart this knowledge, a set of 4-5 different antibiotic disks is sufficient.  Students can place these disks on plates, swabbed with the test organisms, with flame sterilized forceps.  While multidisk dispensers are helpful, they are not essential for teaching the concept.  However, if funds allow it, it is advisable to procure a dispenser so that students can see how this important test is performed routinely in hospitals.

 The recommended manual method for antibiotic sensitivity testing is the Kirby-Bauer method.  Laboratory handouts describing this procedure including a laboratory exercise, are available from this Institute.  For ordering information, see below.

          While the choice of antibiotic discs can vary, Gram positive organisms are generally tested using the following antibacterial agents:

 A-01           Clindamycin 2-mcg

A-02            Lincomycin 2 mcg

A-03            Erythromycin 15 mcg

A-04            Penicillin G 10 units

A-05            Oxacillin 1-mcg   or  

A-06            Methicillin 5 mcg

A-07            Cephalothin 30 mcg

A-08            Tetracycline 30 mcg

A-09            Gentamicin 10 mcg

 Likewise, Gram negative organisms are generally tested using the following antibacterial agents:

 A-10            Ampicillin 10 mcg

A-07            Cephalothin 30 mcg

A-08            Tetracycline 30 mcg

A-09            Gentamicin 10 mcg

A-11            Carbenicillin 100 mcg

A-12            Kanamycin 30 mcg

A-13            Tobramycin 10 mcg

A-14            Amikacin 30 mcg

A-15            Nitrofurantoin 300 mcg

A-16            Trimethoprim 5 mcg  or 

A-17            Sulfamethoxazole 0.25 mg

     Major breakthroughs in microbiology and for that matter in biology since 1960 have been in the field of immunology and serology.  Concepts and skills, especially methodology, of these important areas are, therefore, essential to providing a complete and up-to-date picture of microbiology and biology. Many of these techniques also form the basis of biotechnology and genetic engineering making their learning even more important.

     Unfortunately, reagents used in these areas are produced for use by clinical laboratories and, therefore, are not only expensive, but are often hard to find.  An answer to this dilemma is classroom quality immunological reagents, which are relatively inexpensive.  This catalogue lists such reagents and thus opens ways for instructors to teach a variety of antigen-antibody reactions, such as the precipitin reaction, the agglutination reaction, the complement fixation reaction, the neutralization reaction, the hem agglutination reaction, the passive hem agglutination reaction, immunodouble diffusion or the Ouchterlony reaction and immunoelectrophoresis.  Simultaneously, an instructor can also show how these tests are used in the design of serological tests for the diagnosis of disease, for testing the purity of proteins and other antigens and in medico legal areas such as forensics.

     In addition to providing serological reagents suitable for teaching, the Institute is also available to assist you in the design and implementation of immunological and serological experiments for your classes.  So, feel free to call the Institute with your questions and comments.

     DETAILED LABORATORY HANDOUTS explaining the principles and procedures of immunological and serological reactions are also available from the Institute.  For price information, please refer to the end of this section.

Prepared slides have a special place in teaching microbiology for they enable a student to acquire an appreciation of cellular structure.  Cytological studies of this nature also enable a student to develop an ability to search for detail, to identify special structures and to relate structure with function.  This form of exercise thus enhances comprehension and prepares one for further scientific pursuits.  Furthermore, when a student eventually prepares his or her own slides, the experience gained with prepared slides enables the student to judge and improve his or her technique.  Manual dexterity and neatness gained through such exercises is extremely vital for becoming a good scientist.

Biochemical tests are the heart of microbiological laboratory procedures.  These teach not only the basis of microbial identification but also Chemistry and Biochemistry.  From the philosophical standpoint, these procedures reveal that life is possible with varying degrees of biochemical and biological diversity.  Appreciating these parameters of life thus enhances a student's understanding of life.  Additionally, these procedures help students understand their own nutrition and thus aid in healthful living.


These procedures are also important for understanding genetic engineering for it is these procedures which help select strains with biochemical traits of special interest.  Markers which may aid pathogenesis are also studied via similar procedures.




The following reagents for biochemical tests are supplied prepared, ready to use in screw cap bottles.  Prices and quantities are as shown.  A booklet describing selected biochemical tests is also available at $ 5.00 each.  See below.

Since 1960 emphasis has been shifting to rapid identification of micro-organisms using micro technics and multiple test procedures.

           Conventional procedures using media contained in test tubes and Petri plates were found to be too cumbersome, time consuming and uneconomical.  Consequently, mini methods using just one isolated colony as the inoculum were developed.  These methods speed up the identification procedures and provide diagnostic information in less time than the conventional methods.  They also use less space and are standardized so that persons with a limited training can perform these procedures on a routine basis.

           The first such method which became popular was the Enterotube method.  Subsequently, other methods such as the API followed.

           Concurrently, methods using multiple inoculating devices were also introduced.  These methods have the advantage in that they use conventional procedures and, therefore, do not require retraining of personnel.

           Since rapid test procedures are becoming more popular and are likely to be the methods of the future, it is suggested that a good microbiology course include, at least as demonstrations, some of these rapid and multitest procedures.

Teaching laboratories often get over equipped by purchasing too many unnecessary items of glass and plasticware and other laboratory supplies.  In order to curatail this waste a description of what is essential for teaching a comprehensive course in microbiology is provided below.  Adhering to these guidelines and limiting purchases to what is absolutely essential can cut costs drastically.  Some of these essential supplies are supplied by the institute (see page 30 for description of items and their catalogue numbers).


Test Tubes

  A microbiology teaching laboratory will do well by selecting disposable screw cap tubes of the following sizes:


13 x 100 mm

16 x 100 mm

16 x 125 mm

16 x 150 mm

20 x 150 mm


Of these, the most versatile size is 16 x 150 mm and a fairly large supply of these should always be kept on hand.  These should be used for maintaining cultures and for preparing various types of media.  The use of plain tubes without screw caps for these purposes is wasteful as they accelerate dehydration of media and cultures and thus increase costs.  These tubes also require the use of various sizes of closures or cotton plugs which consume both time and space and thereby increase costs.


A microbiology laboratory however, should have some supply of plain disposable test tubes.  The following sizes are recommended:


 6 x 50 mm       for use as gas vials and for precipitin reactions

10 x 75 mm       for titration purposes

16 x 150 mm    for general purpose use

20 x 150 mm    for general purpose use


A limited supply of 16 x 150 mm pyrex plain and screw cap tubes is also desirable to have on hand, especially when specimens need to be boiled in a water bath for a long period of time.  Disposable tubes will stand temperatures in a boiling water bath for a short period of time and thus can be used for preparing deeps which need to be melted prior to use.


Selecting mostly screw cap tubes and a few plain tubes also does away with the need of purchasing and storing test tube closures, as mere non-absorbent cotton can be used in place of these closures.  This leads to an additional cost saving.  Also, while disposable glassware is referred to as such, it almost always can be sterilized, washed, and reused.


Petri dishes


Disposable plastic Petri dishes of 15 x 100 mm size are still the best buys.  Subsequent to use, these should be autoclaved and discarded.  These are available from the institute.


           A microbiological laboratory should also have a few 20 x 150 mm glass Petri dishes.  These come in handy for immunological work such as incubating double diffusion plates and immunoelectrophoresis plates.  But if you do not have these, standard plastic Petri plates would do fine.


Slides, cavity slides, and cover slips


Slides:  Precleaned slides with one end frosted on one side are the best buys for classroom purposes.  Specimens can be identified by writing with an ordinary lead pencil on the frosted edge.  This also helps students to know as to which side the smear was prepared, thus avoiding problems with focusing under the oil immersion lens.  Slides turned upside down cannot be focused under oil immersion because the lens cannot get close enough to the specimen.


Used slides should be discarded.  Cleaning and reusing them is not only time consuming but also suffers from the drawback that smears can never be completely removed from them.  Such residual smears add confusion when newly prepared smears on these slides are to be examined.  For instance, smears of pure cultures of Gram negative organisms made on slides previously used for making smears of Gram positive organisms will appear mixed as both Gram negative (new) and Gram positive (residual) cells will be seen.


Cavity slides:  Use single cavity slides.  Since cavity slides are expensive, these should be reclaimed.  It is best that students discard these into a separate container containing a detergent solution.  Used slides should be autoclaved prior to washing.


Cover slips:  The most versatile size is 22 x 22 mm rectangular cover slips of number 1 thinness.




Erlenmeyer flasks of 500 ml and 1,000 ml capacity are recommended sizes.  It is also advisable to have a few 250 ml capacity Erlenmeyer flasks.


Round bottom, Florence or other similar flasks are superfluous.




Glass or plastic beakers of 50 ml, 100 ml, 250 ml, 500 ml, and 1,000 ml capacity are recommended sizes.  Glass should be preferred over plastic.


Graduated cylinders


Cylinders of 100 ml, 250 ml and 1,000 ml capacity are recommended sizes.


Volumetric flasks


Volumetric flasks with ground glass stopper of 100 ml, 250 ml, 500 ml, and 1,000 ml capacity are recommended but these are not essential.




Glass disposable pipettes which can be cleaned and reused a few times are the best buys.  For classroom purposes, 1.0 ml and 10 ml sizes of serological pipettes are recommended.  The useful life of disposable glass pipettes can be increased provided the pipettes are not left soaking in the detergent or the disinfectant solution for unnecessarily long periods of time.


Syringes and Needles


Syringes: 1.0 ml, 5.0 ml, 10.0 ml, and 30 ml plastic sterile disposable syringes are the best buys.  It is also advisable to have a few 50.0 ml glass syringes.  All syringes should be equipped with Luer locks.

Needles:  22 gauge 1 inch long and 18 gauge 1-1/2 inches long, sterile disposable needles are recommended as these are versatile sizes.


Centrifuge tubes


          While there are a variety of centrifuge tubes, the best suited for microbiological and general purpose work are the Corex brand tubes.  These are made of glass and are sturdy enough to withstand sufficiently high speeds of centrifugation.  Recommended sizes are 15.0 ml and 25 ml sizes.  Use only the screw cap centrifuge tubes.

           Among plastic centrifuge tubes, those made of polypropylene are recommended as these are autoclavable.  The sizes recommended are 10.0, 30.0 and 48.0 ml capacity.  These should be screw cap tubes.


Filter flasks


250 ml, 500 ml and 1,000 ml sizes are recommended.  The 500 ml size is most versatile.




Glass and plastic funnels of approximately 100 mm top ID each are most useful.  Similar size stainless steel funnels are also useful.  These funnels take a filter paper of 185 mm diameter.  To keep funnels of different sizes is wasteful.  It is good to have a few Buchner funnels though.


Membrane (bacteriological) filters


These are essential but expensive items and if not purchased by first reviewing your needs, can run into considerable expense.  We have found that the preassembled disposable filters of 25 mm diameter, which attach to syringes, are the best buys.  Those which attach to syringes but which you have to assemble yourself are uneconomical, for these are not only time consuming, but one often loses their parts.  This is an additional expense and an aggravation, for one has to check the catalogue to find which parts are lost and also to ascertain which is the correct way of assembling them.  Faulty assembly causes leakage and the filtrate obtained from poorly assembled filters can never be sterile.


The preassembled disposable filters described above are useful for filter sterilizing small quantities of fluids only.  For larger quantities one needs to have larger filters and there is a diversity of sizes available.  But for classroom purposes, filters of 47 mm dia., which fit into a glass or plastic filter assembly, are the most versatile as these can be used for sterilizing liquids as well as for testing water sewage and other liquids.  The funnel of these filters has a capacity of about 250 ml and this is sufficient for most classroom needs.  These filters, however, are to be assembled and sterilized, but if you limit their purchase to one size and brand, the problems due to assembly and lost parts are manageable.


For filter sterilizing, filters of 0.2 micron pore size are the best.  The Institute thus recommends and supplies filters of only this pore size - see page 30 for price information.

The Institute provides a detailed laboratory manual which covers more ground in a short period of time than other manuals.  It covers the entire discipline of microbiology - both basic and applied - and thus enables the student to grasp the essense of this subject quickly and thoroughly.  The manual is divided into 10 study units which are:

1.            Introduction to microbiology and microscopy

2.            Major groups of microorganisms, their identification and cultivation

3.            Bacteria in our environment - isolation and pure culture techniques

4.            Staining characteristics and cytological features of bacteria

5.            Biochemical activities of bacteria

6.            Identification and classification of bacteria

7.            Immunology

8.            Clinical microbiology

9.            Industrial and sanitary microbiology

10.          Virology, molecular biology, and genetic engineering


As you can see, nothing meaningful is left out.  Rather, more material is covered than is generally covered in most other manuals.  The concept of 10 study units provides sufficient time during a quarter, and even more during a semester, to cover the units without undue pressure.  In fact, other manuals, which have 30 - 40 laboratory exercises put the instructor and the students under undue pressure expecting them to complete at least one exercise during each laboratory session.  The instructor and the students thus feel pushed to complete the exercise which leaves no time for discussion.  The learning process is thus grossly short-changed.


In contrast, the unit concept presented in this manual allows a minimum of one whole week to cover one unit.  The unit includes not only the laboratory sessions, but other pertinent material also.  As a matter of fact, relevant material in sufficient detail is presented such that some instructors may find additional textbooks unnecessary.  A schedule of 2 to 3 three-hour sessions per week has worked well with lectures, demonstrations, discussions, and laboratory experiments all done during these hours.   


Another feature of this manual is that it considers memorization of material detrimental to learning.  Emphasis is, therefore, placed on acquiring, understanding, and using concepts, techniques, and skills. This is done through assignments included in the manual which the student completes and hands in to the instructor for comments and possible grading. A systematic atmosphere of learning is thus generated.  For the same reason, the objectives of each unit are clearly listed in the beginning of each unit. These serve as a checklist of goals to be achieved and help contain the vastness of the subject within the grasp of comprehension.


Laboratory supply kits containing all the materials  needed to complete each unit by a class of up to 30 students are also available from the institute.  They take the bother out of setting up the laboratory.  In most cases all you need to do is open and display the contents of the kit and proceed with teaching.  Together with the manual, they enable you to be a more effective teacher. You, of course, do not have to buy the kits. The manual provides detailed lists of supplies needed for each unit.  This gives you the option of checking your own stock and purchasing only the supplies you need.  The manual can thus be used with or without the kits.  In either case all of the supplies you need are available from the institute making their procurement easy.  

The manual is available from the Institute at $20.00 each.
