To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

The operation of the NVDM-100 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-100 diffusion pump is a cap with a cooling tube soldered onto it with fittings. The open heater of the NVDM-100 diffusion pump is a metal housing with a ceramic base laid in it with a heating element made in the form of a spiral 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 mm Hg). Water at the inlet to the cooling systems of the housing and oil reflector should 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 35+5 l/h and is regulated by the outlet water temperature, which should not exceed plus 40˚C. 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 35 Pa (0.263 mm Hg). The level of the working fluid during operation, at which the parameters of the NVDM-100 diffusion pump are provided, must correspond to min 7mm, max 11mm. The volume of the filled working fluid is 0.07/

The 2ZVE-160R vacuum shutter with electromechanical drive equipped with 160mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6 to 1.07x105 Pa (0.75x10–8 to 800 mm Hg). The 2ZVE-160R shutter is pendulum-type. The 23VE-160R shutter is manufactured in the climatic version UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire and explosive hazardous industries. The 23VE-160R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

The NV-1500 SM is a specialized table for microscopy. The table top is 70 cm deep and is made of laminate. It is designed for sitting work: the height from the floor to the countertop is 75 cm (this is the height of a regular office desk). External dimensions of the table (W×D×H): 1500×700×750 mm. A small superstructure allows you to compactly place the necessary drugs and accessories next to the workplace. Its dimensions: (W×D×C): 668×120×200 mm. The table top is made of laminated chipboard. It is relatively moisture-resistant, resistant to short-term exposure to acids, alkalis and organic solvents and is well suited for the placement of devices. The side laminated panels of the table (chipboard 16 mm thick) are edged with a PVC edge 2 mm thick, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor.
