ConFlat (CF) standard connections are used to ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.

The operation of the NVDM-250 diffusion pump is based on the capture and transfer of the pumped gas by a steam jet flowing from the slit gaps of the steam line nozzles towards the outlet flange. The oil reflector of the NVDM-250 diffusion pump is a flange with a cooling tube passing through it, soldered to a cap located in the center of the flange. The NVDM-250 open-type diffusion pump heater is a metal housing with a ceramic base laid in it with a heating element in the form of a spiral made of nichrome wire. During the operation of the pump, it is necessary to monitor the flow rate and temperature of the cooling water, the level of the working fluid and its temperature. Replacement or refilling of the working fluid depends on the operating mode of the pump (inlet pressure, pumping duration, etc.) and the composition of the pumped medium. Therefore, the time after which the working fluid is replaced or refilled can be from 100 to 1000 or more hours. A large flow rate of the working fluid is observed when the pump is operating in the range of inlet pressures from 6.6 × 10-2 to 13.3 Pa (from 5 ×10-4 to 1 ×10-1 mmHg). Water at the inlet to the cooling systems of the housing and oil reflector must be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 4°C to plus 25°C. The recommended cooling water consumption is 100+15 l/h and is regulated by the outlet water temperature, which should not exceed plus 400C. The water drain should be free (with a jet break). Not allowed: operation of the pump without water cooling, exceeding the maximum exhaust pressure of 33.3 Pa (0.25 mmHg) The level of the working fluid during operation, at which the parameters of the pump NVDM-250 are provided, must correspond to min 8mm, max 13mm. The volume of the filled working fluid is 0.55 l

Drying cabinet with manual vacuum adjustment on the front panel SNVS-90/3.5 for heat treatment of materials at temperatures up to 350 ° C (optionally up to 500 ° C) Convenient vacuum control on the front panel. Regulation and air intake by manual taps with smooth opening. Such regulation is convenient when processing sensitive materials.

It is designed to search for leaks of freons and other halogen-containing gases, for example, gas, in working equipment, and when testing systems, including cable ones, for tightness. The GTI-8 halogen leak detector also allows detecting an increase in the concentration of such gases in the room or near the controlled object.

The electric furnace is designed for various thermal processes of annealing, degassing, sintering and other processes in vacuum at temperatures up to 1600 ° C and small gas emissions, in which there is no interaction of the residual gas medium with heater materials, screen insulation and other structural elements.

The vacuum membrane pump PL.HM02.01.4 is a universal device made in Russia from the Primelab company. Made from high-quality materials, including fluoroplastic, used to create sealed chambers, and a protective coating for safe operation of the device. The technical characteristics of the pump depend on the method of connecting the chambers. With a series connection, the performance will be 38 l/min at a maximum vacuum of 4 mbar. Parallel and independent connections will allow you to achieve completely different performance indicators of the device. The vacuum diaphragm pump PL.HM02.01.4 Primelab is convenient to use. It has a light weight of 9 kg, compact dimensions (321.5x160x200 mm) and creates a minimum of noise (up to 75 dB).

The operation of the NVDM-160 diffusion pump is based on the capture and transfer of the pumped gas by a steam jet flowing from the slit gaps of the steam line nozzles towards the outlet flange. The oil reflector of the NVDM-160 diffusion pump is a flange with a cooling tube passing through it, soldered to a cap located in the center of the flange. The NVDM-160 closed-type diffusion pump heater consists of tubular electric heaters fixed in the heater housing. During the operation of the pump, it is necessary to monitor the flow rate and temperature of the cooling water, the level of the working fluid and its temperature. Replacement or refilling of the working fluid depends on the operating mode of the pump (inlet pressure, pumping duration, etc.) and the composition of the pumped medium. Therefore, the time after which the working fluid is replaced or refilled can be from 100 to 1000 or more hours. A large flow rate of the working fluid is observed when the pump is operating in the range of inlet pressures from 6.6×10-2 to 13.3 Pa (from 5×10-4 to 1×10-1 mm Hg). Water at the inlet to the cooling systems of the housing and oil reflector must be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 40C to plus 250C. The recommended cooling water consumption is 60+10 l/h and is regulated by the outlet water temperature, which should not exceed plus 400C. The water drain should be free (with a jet break). Not allowed: operation of the pump without water cooling, exceeding the maximum exhaust pressure of 33.3 Pa (0.25 mm Hg). The level of the working fluid during operation, at which the parameters of the NVDM-160 pump are provided, must correspond to min 10mm, max 17mm. The volume of the filled working fluid is 0.3 liters
