[Thermal characteristics of the thermostat 2TG-0-05 for plates].

The paper is concerned with the results of thermotechnical testing of the Soviet thermostat 2T gamma-0-05 for plates. The thermostat employs dry air, preheating, circulation. As to the productivity, accuracy of the preset temperature maintenance, uniformity of the field of temperatures in the working area of the chamber, intensity of heat exchange of the air flow with the samples in plate cells, the 2T gamma-0-05 thermostat compares very favourably with foreign analogs.

[Unit for preparing the reaction mixture in a semiautomatic biochemical system].

A special unit is developed to operate in the semi-automatic biochemical set. It provides mixing and thermostatic control of a reagent mixture necessary for biochemical studies. To hold the thermostatic liquid at the preset temperature (37 degrees C +/- 0.
