Jingxin Portable Liquid Nitrogen Freezing Grinding Machine is powerful, it is the world's technologically leading liquid nitrogen freezer grinding equipment, the whole process runs at ultra-low temperature, and it is recognized as an efficient grinding equipment in the market: its freezer grinding method is an advanced and efficient , Convenient sample processing method, which can handle samples that are difficult to handle by conventional methods, such as: plastic, rubber, resin, leather, hair, bone, wood, textile materials, etc., which is called the ultimate means of grinding. Liquid nitrogen cryo-grinding instrument has a wide range of applications, such as RNA/DNA detection in biochemistry, polymer structure analysis, determination of trace elements, food analysis, mineral research, medical and surgical assistance, drug performance testing, textile composition Identification and so on
Advantages and characteristics of liquid nitrogen cryogenic grinder:
1. Grinding at low temperature maintains the activity of biological substances, ensures the retention of volatile substances, prevents thermal degradation of thermally unstable compounds, and maintains original sensitivity to metabolites, isomers and complex compounds that are sensitive to thermal and mechanical pressure Characteristic substance.
2. Sample processing is uniform and repeatable.
3. The certainty after setting the grinding parameters makes the sample processing comparable.
4. Sample processing is convenient, fast and efficient.
1. Data accuracy and reproducibility are high;
2. The sample is always at the temperature of liquid nitrogen during the grinding process;
3. During the whole grinding process, the samples are in an independently sealed, ultra-low temperature state, and the integrity of the samples can be preserved to avoid cross-contamination between samples and ensure the control of dangerous and important samples;
4. The cleaning of the sample bottle is very convenient and has high durability;
5. The touch screen is used to set and control the pre-cooling time, grinding time, cycle period, operating frequency of the bumper and other parameters, as well as the entire working process of the instrument. 36 groups of data can be pre-stored for easy recall;
6. It adopts portable design, small body, and has a variety of grinding combinations for users with different application requirements to choose;
7. The instrument has extremely low failure rate, extremely high durability, reliability and safety.
