JXFSTPRP MiniCL Immersion Liquid Nitrogen Cryogenic Grinding Instrument Introduction: At high temperatures, some substances (such as rubber, heavy metal elements, aromatic hydrocarbons, and food) are prone to denaturation, decomposition, and volatilization. However, low-temperature crushed samples will not lose volatile substances and sensitive sample substances due to friction heating, and can retain volatile substances in a closed grinding tank. Some materials such as bones, teeth, seeds, animal and plant tissues, hair, etc. have strong physical toughness and are difficult to crush. Low temperature grinding can perfectly preserve the structure and composition information of the sample, as well as its biological activity. Cell lysis can eliminate sample degradation and avoid damaging DNA and RNA. The choice of cryogenic grinding technology has become a key means of preserving the physical and chemical integrity of samples because low temperatures increase the brittleness of many tough and elastic samples, making them easier to crush, mix, and homogenize. characteristic: 1. Grinding at low temperatures maintains the activity of biological substances, ensures the retention of volatile substances, prevents the thermal degradation of thermally unstable compounds, and preserves the original sensitive properties of metabolites, isomers, and complex compounds that are sensitive to heat and mechanical pressure. 2. The sample processing is uniform and consistent, with good repeatability. 3. The determinacy after setting the grinding parameters ensures comparability in sample processing. 4. Sample processing is convenient, fast, and efficient. 5. High accuracy and reproducibility of data; During the grinding process, the sample remains in liquid nitrogen at all times; During the entire grinding process, the samples are in an independent sealed and ultra-low temperature state, preserving their integrity and avoiding cross contamination between samples, ensuring control over hazardous and important samples; 8. The cleaning of sample bottles is very convenient and has high durability; 9. Using a touch screen display, parameters such as pre cooling time, grinding time, cycle time, frequency of collision operation, and the entire working process of the instrument can be set and controlled. 36 sets of data can be pre stored for easy access; 10. Adopting a portable design, the volume is extremely small, and there are multiple grinding combinations available for users with different application needs to choose from; 11. The instrument has high durability, reliability, and safety.
