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). Cultivator KVM-05 is a long-lived among cultivators of this purpose and a standard of reliability, reproducibility and durability. Used in techniques: - Methodology for determining the toxicity index of nanopowders, products made of nanomaterials, nanopoints, waste and sewage sludge containing nanoparticles by changing the optical density of the Chlorella algae test culture (Chlorella vulgaris Beijer). FR.1.39.2010.09103; MVI 1/25-2010. - Methodology for determining the toxicity of samples of surface fresh, groundwater, drinking water, wastewater, water extracts from soil, sewage sludge and waste by changing the optical density of the chlorella algae culture (Chlorella vulgaris Beijer). MON F T 14.1:2:3:4.10-04 / 16.1:2.3:3.7-04 FR.1.31.2009.06642. - Methodology for determining the toxicity of drinking, natural and wastewater, water extracts from soils, sewage sludge and waste by changing the relative index of delayed fluorescence (OPF) cultures of chlorella algae (Chlorella vulgaris Beijer) HDPE F 14.1:2:4.16-09 / 16.1:2.3.3.14-09.

This cultivator is an improved model of cultivators of the KVM type of earlier execution. Previously, KVM cultivators had a narrowly focused orientation to the Grigoriev Yu.S. methodology. 14.1:2:3:4.10-04 / 16.1:2:2.3:3.7-04; FR.1.31.2009.06642 (biotest on the reaction of a thermophilic strain of chlorella algae, test function - cell growth in relation to control. the duration of the test is 22 hours, toxicity criteria: 20% suppression of growth. 30% - stimulation of growth in relation to control). The Europolitest company strives to provide Russian laboratories with the best equipment with extensive functionality. Today. we have released a new cultivator KVM-08 with touch control. It can still be used according to the above method (in the same mode - power from the 220V household network via the power supply) At the same time, this cultivator can be connected to the on-board network of climatostats (P2, B3 and B4). In this case, it can maintain the temperature control at the level of 20 gr. With (despite the fact that the climatostat will be configured to maintain 18 gr. S). That is, when connecting this cultivator with the on-board network of the climatostat, the cultivator allows you to work in a wider temperature range (20 - 32 gr. S) And when working from 220V - in the range (27 - 40 gr. S.) In such a way thus, this cultivator allows you to consistently carry out two techniques: 1). 14.1:2:3:4.10-04 / 16.1:2:2.3:3.7-04; FR.1.31.2009.06642 (when operating from 220 V without using a climatostat) 2). RD 52.24.905-2020 (when the cultivator is connected to the on-board network of climatostats (P2, B3 and B4) In addition, with new characteristics and functionality, this cultivator is a convenient research tool. In addition to the preset modes for biotests according to the two above methods, the cultivator has 3 three user modes for free programming by the operator Allows you to configure and "flash" individual parameters: - temperature control : any value from the range of 20 - 40 gr. C (take into account the restrictions for work from 220 or from the board. climatostat networks) - lumostating : the maximum value is 16,000 Lux, the cultivator allows you to adjust from 0 to 100 % - rotation speed of the drum with penicillin vials (24 pcs.) : 0 - 60 rpm - duration of exposure: 0 - 240 h (discreteness of 1 min) - sound notification of the end of the specified exposure time

Functional features Working volume 250l. Maintenance of a wide temperature range in the working area (from -5 ° C to 50 ° C). LED lighting with variable spectrum and intensity. Multi-zone lighting distributed over the working volume. Four removable shelves. Execution of the working chamber: stainless steel. A two-door system for the possibility of surveillance. Multi-zone temperature monitoring. Control of the moisture content in the soil. Color TFT display.

The principle of operation of the device UER-03: The principle of operation of the device is based on the creation of equal conditions for all exposed samples during biotesting. It is achieved by rotating the cassette with the test culture samples of crustaceans installed in it around the central axis. Since the sample cassette is oriented obliquely, when it rotates, there is an active gas exchange between the surrounding air and water samples. As the result, test organisms in test tubes are provided with sufficient oxygen concentration in the medium during the entire exposure period. The rotation speed of the cassette is chosen so as not to have a stress effect on the crustaceans. The device operates in continuous mode and does not require additional intervention in the process of exposing the crustacean culture. The required conditions for temperature and light irradiation can be provided only when the device is installed in the climatostat. Used in techniques: - Methodology for determining the toxicity of water extracts from soils, sewage sludge and waste, drinking, sewage and natural water by the mortality of the test object (Daphnia magna Straus). MON F 14.1:2:4.12-06 / 16.1:2.3.3.9-06 FR.1.31.2009.06641. - Methodology for determining the toxicity index of nanopowders, products made of nanomaterials, nanopoints, waste and sewage sludge containing nanoparticles, according to the mortality of the test organism Daphnia magna Straus. FR.1.39.2010.09102 And it can also be used in other suitable techniques.
