It is a special, fast, efficient, multi-tube consistent system. It extracts and purifies raw DNA, RNA and proteins from any source, including tissues/organs, bacteria, yeast, fungi, spores, paleontological specimens, etc. of soil, plants and animals.
The DHTISSUE-192 multi-sample grinder has the advantages of versatility, efficiency and flexibility compared to other existing sample preparation methods. The system avoids the laborious, time-consuming, inefficient and other disadvantages of traditional methods such as grinding, homogenization and ultrasonic treatment, and can efficiently and quickly and stably cleave and purify nucleic acids and proteins of various types of samples.
Grindable samples:
1. Plant tissue: roots, stems, leaves, flowers, fruits, seeds, etc.
2. Animal tissue: brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph nodes, muscles, bones, etc.
3. Fungal bacteria: yeast, E. coli, etc.
4. Food and Drugs: All kinds of food, pills, etc.
5. Volatile samples: coal, oil shale, wax products, etc.
6. Plastics, polymers: PE, PS, textiles, resins, etc.
Multi-sample grinder, DHTISSUE-192 uses a special vertical vertical vibration mode, through the high frequency reciprocating vibration, impact, 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.
Processing capacity The maximum throughput in 15 seconds can handle 24 samples at the same time, including liquid nitrogen refrigeration adapters for 12 and 24 positions.

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.
