When analyzing gases dissolved in transformer oil using the ARP method (equilibrium vapor analysis), mixing of the contents of the syringe with oil is used to accelerate the extraction of gases (to achieve an equilibrium distribution of gases dissolved in oil between the liquid and gas phases). For this purpose, as well as automation of the mixing process, a special autonomous device for achieving equilibrium is produced. technical specifications The rotation speed of the syringe drum is 30 rpm./min. The rotation time (determined by the internal timer, after pressing the "Start" button) is 10 minutes. The number of syringes placed is 4. The volume of syringes is 20 or 50 ml. Power consumption, no more than — 14 VA. Overall dimensions, no more than 210×280×270 mm. Weight, not more than — 5 kg.

The principle of operation of the mill is based on grinding the product with a steel knife rotating at high speed in combination with cyclic rotation of the grinding unit. FEATURES: 1.Fast and high-quality grinding of solid products The high power of the electric motor in combination with a specially designed knife of a special shape and automatic cyclic rotation of the grinding unit of the mill at 210 and 90 makes it possible to qualitatively grind samples of solid products in a short time. It is possible to grind lump cake up to 20 mm in size. 2. Sample preparation without heating. Improved heat dissipation due to the design of the grinding cup, the outer surface of which has the appearance of a radiator, high grinding speed and the possibility of cooling the grinding bowl prevent possible overheating of the sample, which eliminates moisture loss and allows the mill to be used for sample preparation during analysis to determine the moisture content of products. They are part of the installation of the measuring air-thermal ASESH-8 (RU.C.31.005.A No. 56847). According to the test results of FSUE "UNIIM", the mills are recommended for sample preparation during the analysis to determine humidity. 3. COOLING SYSTEM without forced water cooling. For continuous comfortable operation with the cooling system, the mill is equipped with two grinding cups. 4. Quick and easy cleaning of the mill. A mode for grinding solid products with an improved cleaning system of the grinding chamber has been implemented. 5.Grinding headset with long service life The grinding set of the mill is specially designed to work in extreme conditions – high productivity and high mechanical load. Special inserts made of knife-hardened stainless high-strength steel with the effect of forging the grinding chamber and cup ensure long-term operation of the mill when grinding solid and granular products. The knife made of high-strength stainless knife steel guarantees their high wear resistance.

The principle of operation of the mills is based on the grinding of the product, rotating at high speed with a knife in combination with a cyclic rotation of the grinding unit. In order to achieve uniform grinding and homogenization of the sample, the grinding unit must be tilted during grinding. The angle of inclination is set automatically according to the selected mode. FEATURES: 1. Programmable grinding modes The laboratory mill has two grinding modes: "Sunflower" - used for grinding oilseeds. "Grain. Feed" is used for grinding grain, leguminous crops, feed and raw materials for their production. Depending on the crushed product, the operator selects the desired mode of the grinding process. The installation of the grinding mode options is carried out using a specially developed program via a PC. It is possible to install an additional grinding mode using a PC. 2.Easy operation with information display. 3. Crushing of samples with a high fat content (up to 55%). 4. Sample preparation without heating. The special design of the grinding chamber (grinding is carried out in the upper bowl made of aluminum) and the use of special knives ensure rapid grinding and minimize heating of the sample, which eliminates moisture loss. According to the test results of FSUE "UNIIM", mills are recommended for sample preparation during the analysis to determine humidity. They are part of the installation of the measuring air-thermal ASESH-8 (RU. p.31.005.A No. 56847). 5. COOLING SYSTEM without forced water cooling. For continuous comfortable operation with the cooling system, the mill is equipped with two grinding cups. 6. Grinding of various types of samples. The presence of knives of various geometries and the possibility of their quick replacement when changing the crushed product, allows the mill to be used for grinding a wide range of agricultural products – from wheat grains to soybeans and sunflower seeds, according to specially developed algorithms. Knives are included in the delivery package of the mill: knife No. 2 – for grinding oilseeds and cereals; knife No. 4 – for grinding feed and raw materials for their production; knife No. 1 – designed for chopping soybeans.

The Europolitest company continues to release its "bestseller" cultivator KVM-05. This cultivator was developed and produced jointly with the Candidate of Biological Sciences prof. Grigoriev and LLC "Omikron", LLC "SFU-System" Krasnoyarsk. Since 2021, due to the reorganization of the production chain, the production of cultivators of the KVM series has been established by Europolitest LLC in the mode of a full production cycle. The thermophilic strain of chlorella algae has been widely used in ecocontrol laboratories, biotests with this test object are by far the most automated biotests that allow reducing time at all stages of work (building up the uterine culture, sample exposure in the biotest, registration of the test function).

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.
