CryoGrinder LM200 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 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. The automatic control function of liquid nitrogen content avoids the contact and danger of manual opera-tion.
