introduction：shanghai jingxin jxfstprp-cln cryogenic grinder is a fast and efficient, multi-test tube consistent system. it can extract and purify the original dna, rna and protein from any source .
product description: main overview：
shanghai jingxin jxfstprp-cln cryogenic grinder is a fast, efficient and refrigerated grinding system. it can grind, pulverize, and break the cell walls of soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, and paleontological specimens in a very short time. widely used in life science, medicine, biochemistry, environment, geology, agriculture, forestry, quality inspection, materials and other fields.
jxfstprp-cln product principle：
put the sample and grinding ball into the grinding machine (with grinding jar or centrifuge tube/adapter), under the action of high frequency swing, the grinding ball collides and rubs back and forth in the grinding machine at high speed, and the sample can be completed in a very short time grinding, crushing, mixing and cell wall breaking.
main functions and technical indicators：
1. extract nucleic acid/protein
cryogenically ground samples can effectively inhibit nucleic acid degradation and retain protein activity.
2. analysis of medicinal components
there are often significant differences between isomers of active pharmaceutical ingredients, and cryogenic milling prevents the molecules from degrading due to stress and heat.
3. reduce sample volatilization
cryogenic grinding can significantly reduce the volatilization of the sample and preserve the content of the sample components more completely.
4. grinding tough/hard samples
for difficult-to-grind samples such as high-tough plastics, high-strength plastics, and resins, cryogenic grinding can greatly improve the grinding effect and efficiency.
1. does not destroy the sample components: the grinding temperature can be customized and adjusted, which can effectively inhibit nucleic acid degradation and retain protein activity;
2. refrigeration adjustable: -50 to 37 degrees
3. high throughput throughput: process up to 192 samples at a time
4. easy to operate: built-in program controller, can set parameters;
5. high safety: with safety cover and safety lock, no need to involve liquid nitrogen operation, high safety;
6. no cross-contamination: it is in a fully enclosed state during the grinding process to avoid cross-contamination;
7. low noise: during the operation of the instrument, the noise is less than 55db, which will not interfere with other experiments or instruments.
8. no wearing parts design, electromagnetic locking protection
9. stainless steel inner cavity, easy to clean and disinfect
10. no need for regular maintenance
11. stable repeatability: the same grinding procedure achieves the same effect
12. program can be stored: 10 groups of custom grinding programs can be stored
13. good grinding effect: discharge particle size 5um
