The working condition of the ND-250(P) diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-250(R) diffusion pump is a maximum of 1.8 liters, a minimum of 1.3 liters. The viewing window for visual inspection of the working fluid has labels of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid almost does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-250(R) diffusion pump using the same temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the pump up to 320˚C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 160 l/h, for the oil reflector it is 20 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).

Pasteur sterile pipettes are designed for dosing solutions during serological and bacteriological studies. Relief graduation is applied to each pipette. The calibration scale is 0.5-3.0 ml. The constant diameter of the spout allows you to always get a drop of a given volume. A closed filling tank ensures safe operation.
