DHFSTPRP-48IN Fully automatic liquid nitrogen cryogenic grinder is a special, fast, high-efficiency, multi-tube homogenization system that extracts and purifies raw DNA, RNA, and proteins from any source, including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, and paleontological specimens.
Product Features
Compared with other sample preparation methods currently available, the DDHFSTPRP-48IN Fully automatic liquid nitrogen cryogenic grinder has the advantages of wide applicability, high efficiency, and flexibility. The system avoids the many drawbacks of traditional methods such as grinding, homogenization, and ultrasonic treatment, which are laborious, time-consuming, and inefficient. It can efficiently, quickly, and stably lyse and purify nucleic acids and proteins from various types of samples.

Product Applications
Sample Types for Grinding:
1. Plant Tissues: Roots, stems, leaves, flowers, fruits, seeds, etc.
2. Animal Tissues: Brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph node, muscle, bone, etc.
3. Fungi and Bacteria: Yeasts, E. coli, etc.
4. Food and Drugs: All kinds of food, tablets, etc.
5. Volatile Samples: Coal, oil shale, wax products, etc.
6. Plastics and Polymers: PE, PS, textiles, resins, etc.
DHFSTPRP-48IN Fully automatic liquid nitrogen cryogenic grinder uses a special vertical up-down integrated vibration mode, which achieves rapid grinding of samples through the high-frequency reciprocal vibration, impact, and shear of grinding beads (zirconia, steel, glass, ceramic). This ensures the samples are fully and uniformly ground, and have better sample repeatability with no cross-contamination between samples.
High efficiency with multiple operations and good results Efficient and quick work can be completed within 1 minute for grinding 2x24, 2x48, and 4x96 samples. It saves time and effort, and the differences between batches and within batches are small. The extracted protein has higher activity and the nucleic acid fragments are longer.
No cross-contamination The sample tubes are in a fully enclosed state during the crushing process and can use disposable centrifuge tubes and beads. The samples are kept intact in the tubes, avoiding cross-contamination between samples and external contamination.
Simple operation 1. Built-in program controller, which can set parameters such as grinding time and rotor vibration frequency;
2. User-friendly operating interface.
Good stability 1. Using a vertical oscillation method, the grinding is more complete and the stability is better;
2. During the instrument operation, the noise is less than 55dB, which will not interfere with other experiments or instruments.
Convenient for low-temperature operation When a low-temperature grinding environment is needed, the adapter containing the sample can be immersed in liquid nitrogen for cooling for 1-2 minutes, then taken out and quickly fixed to the main unit for grinding, without the need for further freezing, saving liquid nitrogen.
Good reproducibility The same program set for the same tissue sample yields the same grinding effect. The working time is short, and the sample temperature does not rise.
