Product Applications
Sample for Grinding:
1. Plant Tissues: roots, stems, leaves, flowers, fruits, seeds, etc.
2. Animal Tissues: brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph nodes, muscle, bones, etc.
3. Fungi and Bacteria: yeast, E. coli, etc.
4. Food and Medicine: various food, pills, etc.
5. Volatile Samples: coal, oil shale, wax products, etc.
6. Plastics and Polymers: PE, PS, textiles, resins, etc.
·Nucleic Acid/Protein Extraction
Low-temperature grinding of samples can effectively inhibit nucleic acid degradation and preserve protein activity.
·Analysis of Active Pharmaceutical Ingredients
There are often significant differences between isomers of drug active ingredients. Low-temperature grinding can prevent molecular degradation due to pressure and heat.
·Reducing Sample Volatility
Low-temperature grinding can significantly reduce sample volatility and more completely retain the content of sample components.
·Grinding Tough/Hard Samples
For hard-to-grind samples such as tough plastics, high-strength plastics, and resins, low-temperature grinding can greatly improve grinding efficiency and effectiveness.
DHFSTPRP-CL48 High-throughput cryogenic grinder adopts a special vertical up-down integrated vibration mode, which achieves rapid grinding of samples through the high-frequency reciprocating vibration, impact, and shear of grinding beads (zirconia, steel, glass, ceramics). This results in more thorough and uniform grinding of samples, better sample reproducibility, and no cross-contamination between samples.
High Quantity of Operation with Good Effect Highly efficient and rapid operation can be achieved, with the ability to grind 2×24, 2×48, or 4×96 samples in just one minute. This saves time and effort, and reduces differences between batches and within batches. Extracted proteins have higher activity and nucleic acid fragments are longer.
No Cross-Contamination Sample tubes are fully enclosed during the crushing process, and disposable centrifuge tubes and beads can be used. Samples are kept intact in the tubes, avoiding cross-contamination between samples and contamination from the outside environment.
Easy to Operate 1. Built-in program controller for setting grinding time, vibration frequency of the rotor, and other parameters;
2. User-friendly interface.
Good Stability 1. Uses a vertical oscillation mode for more complete grinding and better stability;
2. During instrument operation, the noise level is less than 55dB, which will not interfere with other experiments or instruments.
Convenient for Low-Temperature Operations When a low-temperature grinding environment is needed, the adapter containing the sample can be immersed in liquid nitrogen for 1-2 minutes for cooling, and then quickly fixed to the main unit for grinding. This eliminates the need for additional freezing, saving liquid nitrogen.
Good Reproducibility The same program settings for a given tissue sample yield the same grinding results. The working time is short, and sample temperature does not rise.
