A viton hose with an internal diameter of 10 mm is used to connect the VTi CRYO-VT series thermostats to external consumers or as a jumper hose. We recommend it for use with PMS heat carriers

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.

It is used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • Parabolic mirror optics are used in the design • Windows-substrates can be placed in the prefix after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • Limited use – in the study of whole samples with dimensions less than 5 mm (preferably using a vertical-type microfocusing attachment)

The filter holder FD-05D is designed to install aerosol and iodine filters in it, in an amount of up to 8 pieces. The filters are arranged sequentially. It is used in sampling systems of gas-aerosol media at radiation-hazardous and other production facilities.

The ZVPlE-630 shutter consists of a housing with connecting flanges, a shutter mechanism, a lip seal to ensure the tightness of the drive element, cover, and electric drive. The shutter mechanism consists of a carriage, an upper and lower flap, which are pulled together by springs and balls. The carriage moves along the housing guides on bearings. The ZVPlE-630 shutter is opened and closed both by electric drive and manually using a flywheel. To switch to manual control mode, there is a switching device on the electric drive. The manual drive is used to adjust and adjust the shutter. ZVPlE-630 valves are manufactured in climatic versions UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69.

It is designed to prevent the flask from surfacing when it is thermostated in a laboratory bath or in a liquid thermostat.

It allows recording transmission spectra of objects with sizes from 500 microns (precious stones, optical parts, semiconductor materials). It is also used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • The design uses parabolic mirror optics • The set-top box is equipped with a set of replaceable diaphragm holders for samples of different sizes • Windows-substrates made of IR-transparent materials can be placed in the holder after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • The slide table has the possibility of smooth movement in vertical and horizontal directions to achieve the maximum signal level

To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45

It is designed to measure sound pressure in the air and is used in noise measuring equipment as a measuring transducer of infrasound, sound and ultrasonic pressure.
