[A DEVICE FOR THE VACUUM TREATMENT OF HISTOLOGICAL MATERIAL].

A device to carry out all types of vacuum infiltration in a wide temperature range. The device is easy to use and allows you to simultaneously conduct the infiltration of a large number of tissue samples. The main element of the device is a temperature-controlled cuvette, the temperature of which is set in the range of 23-65 °C. The design of the cell allows pumping air from the cell to the 50-100 mm Hg. In practice, histological methods are used to remove the vacuum infiltration of air from the tissue fixation (plant tissue), to accelerate the penetration of fasteners into the tissue. To carry out such a procedure, syringes, water pump and other hand-held devicesare used. Only vacuum infiltration allows a fill lyophilized tissue in paraffin. Efficiency of the described device is checked during the experiments at various fixing plant tissue and nervous tissue filling lyophilized in paraffin.
