with the rapid development of science and technology， DNA detection and polymer analysis are becoming more and more important. ln order to maintain the original components and biological information of sam- ples，it is necessary to adopt low-temperature pulverization. cryoGrinder LM200 chills the sample in liquid nitrogen and pulverize them with a magnetically driven impactor. The sample become brittle and the vola- tile components are preserved under the low temperature， so that a good grinding effect can be achieved.
lt is applied to samples with strong toughness and thermal sensitivity that are difficult to be ground and crushed at room temperature， such as rubber， plastic， food， mineral， animal and plant tissue analysis， drug， biochemical DNA detection， cell disruption and other fields.
