5. Volatile samples: coal, oil shale, wax products, etc.
6. Plastics, polymers: PE, PS, textiles, resins, etc.
• Extraction of nucleic acids/proteins Low temperature grinding of samples can effectively inhibit nucleic acid degradation and retain protein activity.
· Analysis of medicinal ingredients There are often significant differences between the isomers of the active ingredients of the drug. Low temperature milling prevents molecules from degrading due to pressure and heat.
·Reducing sample volatilization Low temperature grinding can significantly reduce sample volatilization and preserve sample content more completely.
·Grinding toughness/hard sample For low-hardness plastics, high-strength plastics, resins and other difficult-to-grind samples, low-temperature grinding can greatly improve the grinding effect and efficiency.
Multi-sample rapid oscillating grinder, DHFSTPRP-CL64 uses a special vertical vertical vibration mode, through the high frequency reciprocating vibration, impact and shear of grinding beads (zirconia, steel balls, glass beads, ceramic beads). Fast implementation goals. The ground sample is made more adequate, more uniform, sample repeatability, and no cross-contamination between samples.
A large number of operations and good results. Efficient and fast work can complete 2×24, 2×48, 4×96 samples in 1 minute. It saves time and effort, and there are small differences within batches. The extracted protein is higher in activity and the nucleic acid fragment is longer.
No cross-contamination The sample tube is fully enclosed during the crushing process and disposable centrifuge tubes and beads can be used. The sample is completely retained in the tube to avoid cross-contamination between samples and external contamination.
Easy to operate 1. Built-in program controller, which can set parameters such as grinding time and vibration frequency of the rotor;
2. User-friendly operation interface.
Good stability 1. Vertical oscillating mode, more complete grinding and better stability;
2. During the operation of the instrument, the noise is less than 55dB and will not cause interference to other experiments or instruments.
Convenient for low temperature operation When a low temperature grinding environment is required, the adapter with the sample can be immersed in liquid nitrogen for 1-2 minutes, removed and transferred to the main unit for quick fixing to start grinding. It does not need to be re-frozen and save liquid nitrogen.
Good repeatability The same procedure was set for the same tissue sample to achieve the same grinding effect. The working time is short and the sample temperature does not rise.
Application areas Tissue grinding, homogenization, cell disruption, homogenization, material dispersion, preparation, sample mixing, oscillation, etc.

Precautions before use:
1. The LW kit can be used to extract DNA/RNA protein in samples quickly, efficiently, stably and in batches.
2.1Hz=30 rev / sec / 1Hz = 100RPM
3. Conventional adapters can be placed in the refrigerator to give the sample a cold environment while working. It can be equipped with an adapter with refrigeration and can be immersed in liquid nitrogen for more than 30 minutes.
4. The noise emission value for the working environment depends on the type of sample and the setting of the grinder. The parameters in the table are empty.
5. A small number of samples commonly used for DNA and RNA isolation can be prepared in disposable centrifuge tubes. Adapters made of Teflon can be used to hold 5 or 10 disposable sample tubes for cell disruption. The tissue in the tissue mill is quickly and efficiently broken in a very short time, so no additional cryogenic refrigeration is required.
