Abstract:
For long-term preservation of anatomical specimens, it is important to use materials that are inert and stable in their chemical composition. In this work, a sealant composition has been developed based on products of processing substances of natural origin (beeswax, paraffin, petroleum jelly, rosin) and a plasticizer. Using physicochemical research methods (determination of hardness, weight and melting point), the most stable composition of the components of the sealant during storage was determined (23-30% rosin and 53-60% wax). The sealant manufacturing technology presented in this work is easily accessible in a chemical laboratory.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
