DHCL-6K Three-Dimensional Centrifugal Cryogenic Grinding Mill is a grinder with integrated cryogenic grinding, centrifugation, and three-dimensional functions on the market. It has a fast and efficient, multi-tube system that can extract and purify raw DNA, RNA, and proteins from any source, including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, and paleontological specimens.
Product Principle
The DHCL series cryogenic grinding mill integrates preparation, grinding, freezing, and centrifugation functions. It can also be used as a low-temperature centrifuge. With a maximum speed of 6000rpm, the sample and grinding balls are placed in the grinding mill (equipped with grinding jars or centrifuge tubes/adapters). Under high-frequency oscillation, the grinding balls rapidly collide and friction within the grinding mill, breaking up cells and cell walls of various samples in a very short time, quickly releasing original DNA, RNA, and proteins for subsequent extraction and purification.


Product Features
○ Flexible parameters:
Microprocessor control allows for customization of various reagent kits, with a 5.7-inch color touch screen and easy program settings (up to 99 programs can be saved).
○ Good stability:
With a unique fastening mechanism, sample tube fixation is more convenient. Program calls are fast, with noise levels ≤54db.
○ Professional and efficient:
Sample fragmentation and lysis time is short, avoiding nucleic acid degradation and protein denaturation, ensuring the integrity of extracted nucleic acids or proteins. Innovative design with low-speed, ultra-long continuous operation function (up to 30min), suitable for whole-genome library construction, cloning, and sequencing.
○ Zero sample contamination:
The operation is fully enclosed, avoiding cross-contamination between samples and external contamination.
○ Integrated preparation:
Unique grinding, freezing, and high-speed centrifugation three-dimensional integration function effectively prevents the reduction of sample biological activity due to heat. The highest centrifugation speed is 6000RPM, eliminating many complex transfer operations, and can also be used as a standalone low-temperature centrifuge.
○ High safety and easy maintenance:
Uses a brushless frequency conversion motor that does not produce carbon particles and does not require carbon brush replacement. Long service life, no easily damaged parts, all-stainless steel inner chamber for easier cleaning and disinfection, and no need for dangerous materials such as liquid nitrogen for auxiliary processing.


Product Applications
Sample grinding applications:
1. Plant tissues: roots, stems, leaves, flowers, fruits, seeds, etc.
2. Animal tissues: brain, heart, lungs, stomach, liver, thymus, kidneys, intestines, lymph nodes, muscles, bones, etc.
3. Fungi and bacteria: yeast, E. coli, etc.
4. Food and drugs: various foods, tablets, 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 pharmacological ingredients
There are often significant differences between isomers of effective drug ingredients. Low-temperature grinding can prevent molecule degradation due to pressure and heating.
· Reduce sample volatilization
Low-temperature grinding can significantly reduce sample volatilization and more fully preserve sample component content.
· Grinding toughness/hardness samples
For difficult-to-grind samples such as high-toughness plastics, high-strength plastics, resins, etc., low-temperature grinding can greatly improve grinding efficiency and effectiveness.

DHCL series 3D centrifugal cryogenic grinding machine adopts integrated preparation, grinding, freezing, and centrifugation functions. It can also be used as a low-temperature centrifuge alone. With a maximum speed of 6000rpm, the sample and grinding balls are placed in the grinding machine (equipped with a grinding jar or centrifuge tube/adapter). Under high-frequency oscillation, the grinding balls rapidly collide and friction back and forth in the grinding machine, breaking cells, homogenizing and breaking cell walls of various types of samples in a very short time, quickly releasing original DNA, RNA, proteins, etc., which is convenient for subsequent extraction and purification.


   
High efficiency with a large capacity The DHCL series three-dimensional centrifugal cryogenic grinder can prepare, grind, freeze, and centrifuge samples in one machine, with a high-speed rotation of up to 6000rpm. It can grind 2x24, 2x48, and 4x96 samples in just one minute, saving time and effort while minimizing inter-batch and intra-batch differences. The extracted protein has higher activity, and the nucleic acid fragments are longer, making it easier for subsequent extraction and purification.
No cross-contamination The sample tubes are in a fully sealed state during the crushing process, and disposable centrifuge tubes and beads can be used. The samples remain intact in the tubes, avoiding cross-contamination between samples and external pollution.
Easy to operate 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. Adopting a vertical oscillation method for more thorough grinding and better stability;
2. During 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 samples can be cooled in liquid nitrogen for 1-2 minutes, then removed and quickly fixed onto the main machine for grinding, without the need for further freezing, saving liquid nitrogen.
Good repeatability With the same program settings for the same tissue sample, the same grinding effect can be obtained. The working time is short, and the sample temperature does not rise.


Technical Specifications
