·Extract nucleic acid/protein
Cryogenic grinding of samples can effectively inhibit nucleic acid degradation and retain protein activity.
·Analysis of active ingredients
Significant differences often exist between isomers of active pharmaceutical ingredients. Cryogenic grinding prevents molecular degradation due to pressure and heat.
Reduce sample volatilization
Cryogenic grinding can significantly reduce the volatilization of the sample and preserve the content of the sample components more completely
Grinding tough/hard samples
For hard-to-grind samples such as high-toughness plastics, high-strength plastics, and resins, low-temperature grinding can greatly improve the grinding effect and efficiency
DHFSTPRP-CL24 Frozen Samples homogenizer a special vertical up-down integrated vibration mode is adopted, through the high-frequency reciprocating vibration, impact and shearing of grinding beads (zirconia, steel balls, glass beads, ceramic beads). achieve goals quickly. The ground samples are more complete and uniform, the sample repeatability is better, and there is no cross-contamination between samples.
| The number of operations is large, the effect is good | Efficient and fast work can complete the grinding of 2×24, 2×48, 4×96 samples in 1 minute. Save time and effort, and the difference between batches and batches is small. The extracted protein has higher specific activity and longer nucleic acid fragments. |
| No cross contamination | The sample tube is completely closed during the crushing process, and disposable centrifuge tubes and beads can be used. The sample remains intact 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 rotor vibration frequency; 2. Humanized operation interface. |
| good stability | 1. The vertical oscillation method is adopted, and the grinding is more sufficient and the stability is better; 2. During the operation of the instrument, the noise is less than 55dB, which will not interfere with other experiments or instruments. |
| Convenient low temperature operation | When a cryogenic grinding environment is required, the adapter with the sample can be immersed in liquid nitrogen to cool for 1-2 minutes. After taking it out, move it to the host for quick fixation, and then grinding can begin without re-freezing, saving liquid nitrogen. |
| good repeatability | The same tissue sample was set to the same program to obtain the same grinding effect. The working time is short and the sample temperature does not rise. |

1. The matching LW kit can be used to quickly, efficiently, stably, and batch extract DNA/RNA proteins from samples.
2. 1Hz=30 revolutions/second / 1Hz=100RPM
3. Conventional adapters can be refrigerated to give samples a cool environment while working. It can be equipped with an adapter with refrigeration, which can be soaked 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 settings of the grinder. The parameters in the table are in the no-load state.
5. Small samples typically used for DNA and RNA isolation can be prepared in disposable centrifuge tubes. Adapters made of Teflon material can be used to accommodate 5 or 10 disposable sample tubes for cell disruption. Cells and tissues are rapidly and efficiently disrupted in a very short time in the Multi-Sample Tissue Grinder, thus eliminating the need for additional cryogenic refrigeration.
