With the rapid development of science and technology, DNA detection and polymer analysis are becoming more and more important. In order to maintain the original components and biological information of samples, it is necessary to adopt low-temperature pulverization. CryoGrinder chills the sample in liquid nitrogen and pulverizes them with a magnetically driven impactor. The sample becomes brittle and the volatile components are preserved under the low temperature so that a good grinding effect can be achieved.
Suitable samples include polymers, rubber, textile materials, grain particles, hair, nails, skin, bones, muscle tissue, etc. A strong electromagnetic impact force ensures the effectiveness of grinding. The automatic control function of liquid nitrogen content avoids the contact and danger of the manual operation. CryoGrinder can also be used in dry grinding at normal temperature, so it is an ideal instrument for processing heat-sensitive samples, biochemical DNA/RNA analysis and various sample grinding.
It is applied to samples with strong toughness and thermal sensitivity that are difficult to be ground and crushed at room temperatures, such as rubber, plastic, food, mineral, animal and plant tissue analysis, drug, biochemical DNA detection, cell disruption and other fields.
Size reduction is taken place by electromagnetic oscillation impact. The sample and the metal impactor are loaded into the grinding jar together. The grinding jar is sealed with plug head by the two ends and put into the electromagnetic vibration drum coil. Electromagnetic coil with grinding jar immersed in liquid nitrogen to be pr-cooled. The whole grinding process is carried out in liquid nitrogen (-196 ℃). The magnetic force generated by the coil drives the impactor to move horizontally, thus continuously impact on then grind the sample that has been frozen and embrittled.
