Instrument name:Cryostat Microtome

Model:CM1950

Manufacturer:Leica

Applications:

Used for making frozen slices for biological, medical and industrial applications 。

Instrument main functions:

The CM1950 is a superior cryotome with a fully enclosed microtome and a separate sample refrigeration system. Equipped with UV disinfection system, integrated slice waste suction system, automatic defrosting function. The operation is simple, the tissue can be frozen and hardened quickly, and the sections can besliced without going through the procedures of fixation, dehydration of all levels of ethanol，transparency，and other procedures; Fast, short time; Little change in tissue morphology; Good preservation of fats, lipids and other components; It can preserve various antigenic activities and enzymes relatively well, especially for those membrane surface antigens and hydrolases with poor temperature tolerance to organic solvents or heat.
