Abstract

The invention relates to a grinding device suitable for frozen tissue. The grinding device suitable for the frozen tissue comprises a base, wherein a tool accommodating box is arranged in the base, adrawer-type powder collecting box with an open upper part is arranged on the base, a low-temperature crushing box body penetrating up and down is arranged on the upper part of the powder collecting box, dry ice-type low-temperature ice bags are arranged in four side walls of the box body, a drawable screen is arranged at the bottom of the box body, a sealing cover is arranged at the top end of thebox body, a feeding port is fixedly arranged on the sealing cover, the top end of the feeding port is hinged with a sealing feeding cover, a grinding and crushing mechanism is horizontally arranged in the middle of the box body, and the grinding and crushing mechanism is manually driven to realize low-temperature crushing on the frozen tissue. The grinding device suitable for the frozen tissue has the advantages of simple structure and ingenious design, ensures the activity of an experimental sample, reduces the loss of a tissue sample, protects the safety of experimental personnel, and greatly improves the grinding efficiency.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a grinding device, in particular to a grinding device suitable for frozen tissue. Background technique [0002] Mortars are usually used to grind tissues, which are fine for soft spots such as paraffin, fresh liver, brain, and plant tissues; later, frozen tissues need to be ground, which are -80 degrees or liquid nitrogen quick-frozen tissues, which are very hard , this open mortar or crucible can't grind, the tissue is too hard and brittle, when grinding with a pestle, it will cause the frozen tissue to shatter and splash out of the mortar or crucible. If the grinding time is too long, the tissue will become soft and sticky after heating up. Therefore, there is an urgent need for a grinding device suitable for frozen tissue that can keep the grinding space at a low temperature and ensure that the frozen tissue is kept at -80°C during grinding. [0003] No patent documents relevant to...
