The School of Life Sciences, Nanjing University, Department of Ecology, purchased the LAWSON (Luoshan China) FSTPRP-24 automatic sample rapid grinder, mainly for grinding cyanobacteria to extract RNA. And the adapter with freezing function is placed under liquid nitrogen for freezing, and then grinding, which can ensure that the sample is completely ground, and the grinding time is only 30 seconds, which avoids the problem of RNA degradation. The extracted RNA is mainly used for the advantages of cyanobacteria blooms in Taihu Lake. Research fields such as the action mechanism of biological functional groups in the maintenance process, the photosynthetic physiological characteristics of salt marsh plants and their significance in the vegetation zoning of coastal ecosystems.

LAWSON (Luoshan China) has no significant difference in concentration and purity of DNA and RNA extracted from FT after processing by LAWSON's automatic sample rapid grinder and manual liquid nitrogen grinding. (P > 0.05 for pairwise test). However, manual grinding has a large sample loss rate. For samples with low DNA extraction concentration, the automatic grinder can achieve 0 sample loss, which has obvious advantages in DNA extraction, and the manual processing process is complicated and easy to cross. Contamination, operation time and other aspects are not as good as the automatic sample rapid grinder of LAWSON (Luoshan China), so the automatic grinder has great advantages for DNA extraction work compared to manual grinding.

LAWSON (Luoshan China) is currently the only manufacturer in China that produces horizontal tissue grinders, vertical tissue grinders, and three-dimensional integrated tissue grinders with a full range of production lines. . He is the inventor of the domestic multi-sample tissue grinder and masters the core technology. At the same time, it also provides OEM and OEM processing services to many foreign brands and domestic enterprises.
