The basic cryogenic grinder JXFSTPRP-CL-BSC is mainly used in scientific research fields such as life science, medicine, biochemistry, environment, and geology.

Shanghai Jingxin JXFSTPRP-CL-BSC Cryogenic Grinder is a fast and efficient, multi-tube consistent system. It can extract and purify the original DNA, RNA and protein from any source (including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, paleontological specimens, etc.). This refrigerated grinder adopts a novel appearance design, which is exquisite and compact, with excellent performance, and the grinding temperature can be adjusted by custom, which can effectively inhibit nucleic acid degradation and retain protein activity.

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.

Cryogenic grinder sample range: animal and plant tissues, microorganisms, rock minerals, soil, medicine, chemical polymers, etc.

Features:

1. Does not destroy sample components: the grinding temperature can be adjusted by custom, which can effectively inhibit nucleic acid degradation and retain protein activity;

2. High efficiency: Jingxin polymer material adapter, fully pre-cooling the adapter, can keep it in a low temperature state for more than half an hour. Put the centrifuge tube into the adapter to meet the experimental requirements of cryogenic grinding. This method can process 12*2ML, 6*5ML samples at one time.

3. Good repeatability: set the same procedure for the same tissue sample to obtain the same grinding effect;

4. Easy to operate: built-in program controller, which can set parameters such as grinding time and rotor vibration frequency;

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.

Main Advantages

·Extract nucleic acid/protein

Cryogenic grinding of samples can effectively inhibit nucleic acid degradation and retain protein activity.

·Analysis of active ingredients

There are often significant differences between isomers of active pharmaceutical ingredients, and cryogenic grinding prevents the molecules from degrading due to stress and heat.

· Reduce sample volatilization

Cryogenic grinding can significantly reduce the volatilization of the sample and preserve the content of the sample components more completely

· Grinding tough/hard samples

For hard-to-grind samples such as high-toughness plastics, high-strength plastics, and resins, low-temperature grinding can greatly improve the grinding effect and efficiency.
