Klauss and his colleagues used to put all synthesized substances to the cupboard, and this tradition was kept till the middle of the XX century. Now more than 500 substances, having been obtained by the founders of the Kazan School of Chemistry, are kept in three cupboards.

One of the cupboards contains a unique collection of old chemical vessels - the retorts of different size of 10-50 milliliters, "helmets", i.e. the vessels for liquids distillation, Wurtz retorts, different packings, and Glinsky's dphflegmator (a professor of the Kazan University, known by European chemists).

A.Ye.Arbuzov was not only an excellent experimenter, but also a brilliant glass-blower. He made all the vessels and glass equipment for experiments himself.
The retort, designed and made by him, was known as "Arbuzov's retort" later on. It is produced at the plants under the same name. Besides, there are other various glass equipment in the museum, made by the scientist, and his brochure "Guide to Glass-Blower Learning", published in St. Petersburg in 1912.

Laboratory equipment of the XIX century is exhibited in a separate cupboard in the same hall. There are three analytical scales, made in Germany, hand metal vacuum pump, water baths, hydrogen Debereiren steel for getting sparks without matches, sets of weights made of metal, pycnometer, and a lot of original equipment, which can hardly have copies in laboratories of Russia.

Almost all the researches, done in the laboratory, were the first in Russia.For example, Innokenty I. Kanonnikov and Flavian M. Flavitsky were the founders of using physics methods in chemistry. We can see a set of polarimeter cuvettes, which was used while researching light refraction related to the structure of chemical compounds.
