Nitrogen generators are designed to create an inert atmosphere, fill low-pressure tanks, "rinse" test tubes with inert gas and other applications that require a large, by laboratory standards, nitrogen consumption with reduced requirements for its purity. Technical specifications Volume fraction of nitrogen is not less than % by volume (including impurities of inert gases — argon, neon, helium) 99.6 Volume fraction of oxygen is not more than, % vol. 0,4 Volume fraction of water vapor is not more than, % vol. 0.002 (20 ppm) Maximum nitrogen capacity is at least 200 (3.33 l/min), l/h Maximum nitrogen outlet pressure is not less than 3.5 ati The time of setting the operating mode for single-shift operation is no more than 30 min Nominal inlet air pressure is 6 ati Maximum allowable inlet air pressure is 8 ati Minimum inlet air pressure is 5 ati Compressed air consumption, at nominal inlet pressure and maximum flow rate is no more than, l/h, 1200 (20 l/min) Power consumption is not more than, VA, 100 Overall dimensions (width x depth x height) are not more than, mm, 230x525x510; Weight is not more than 26 kg Working conditions: ambient temperature, C°, from +10 to +35 Electric power supply from single-phase AC mains voltage, V, 220± 10% and frequency, Hz, 50 ± 1 Average full service life is at least 6 years The generator for electrical safety meets the requirements of Class 1, type H according to GOST 12.2.025-76

The ASE-2 energy dispersive sulfur analyzer is designed to measure the mass fraction of sulfur in unleaded gasoline, diesel fuel, crude oil, kerosene, oil residues, lubricating oil bases, hydraulic oils, jet fuels and other distillate oil products. X-ray radiation from a low-power X-ray tube, converted by a primary radiation filter, excites fluorescence emission from the atoms of the sample being analyzed. The fluxes (primary X-rays scattered on the sample and secondary fluorescence) of radiation fall on a gas proportional counter, whereby the fluorescence radiation of sulfur atoms (SKa) is separated from the radiation with other energies by means of selective filters. The intensity of the fluorescence emission of sulfur atoms registered by the gas proportional counter is proportional to the mass fraction of sulfur in the analyzed sample.

Petri dish PrimeLab 120 mm, glass - a small laboratory container with a small edge around the perimeter, made of tempered glass. Consists of two parts with the following features: • The diameter of the upper part is 129 mm with 120 mm of the lower part. • The height of the upper part is slightly lower than the height of the lower part, due to which the upper “lid” fits freely onto the base to protect the contents from the external environment and other microorganisms. • Glass thickness is 2 mm.
