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

According to the requirements of the standards, the cooler is included in the list of equipment for determining humidity with pre-drying. Usually, grain samples after preliminary drying are cooled in the laboratory room to ambient temperature. However, with such cooling, the ambient temperature reaches only the surface layers of the samples, which affects the results of the analyses. The principle of operation of the cooler is based on blowing sample canopies in mesh buckets placed on a stand by a fan rotating at high speed. Advantages: Rapid cooling of samples. Stable moisture distribution. Allows you to significantly improve the accuracy of the results of determining humidity.

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.

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 principle of operation of the electronic diaphanoscope YANTAR is to assess the vitreousness of the image obtained using a digital camera. The vitreous value is calculated using a software-implemented algorithm using special calibration equations. The analysis time is 1 minute. Automation of the vitreous assessment avoids the error associated with the subjective opinion of a specialist. The use of specially developed calibration standards based on optical filters for uniform adjustment of diaphanoscopes permits to coordinate the operation of two or more devices remotely. The interlaboratory error in determining the vitreousness on the devices included in the network does not exceed the standard. All the results of the determination of the vitreousness of wheat with the corresponding grain images are stored in the archive. If necessary, specialists can print the protocols of the current or any of the previous definitions. THE ALGORITHM OF OPERATION: 1. Pour the grains into the cassette and close the lid made of transparent glass. 2. Install the cassette in the diaphanoscope. 3. Launch the program. 4. Choose a product 5. Software processing of the digital image of grains in accordance with the selected product 6. Calculation of computer results. In 2023, a new national standard GOST R "Wheat. Determination of vitreousness by optical-computer method".
