Product Description:

Shanghai Jingxin JXCL-6K 3D centrifugal cryogenic sample grinder (patented product, counterfeit must be investigated! ZL2019206343499, ZL2019206348581) is a sample grinder that combines freezing, grinding and centrifugation. It features a fast and efficient, multi-tube system for the extraction and purification of raw DNA, RNA and proteins from any source including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, archaeal specimens, etc.

Original patented dual-motor centrifugal vibration integrated design

Centrifuge immediately after lysis to obtain supernatant directly

Low temperature and high speed crushing function developed for many years

Operating principle:

1. Put the sample and grinding balls into the grinder (configured with grinding jar or centrifuge tube/adapter);

2. Under the action of high-frequency oscillation, the grinding ball collides and rubs back and forth in the grinding apparatus at high speed, and in a very short time, various samples are subjected to cell disruption, homogenization and cell wall breaking;

3. Quickly release the original DNA, RNA and protein, etc., to facilitate subsequent extraction and purification;

Application:

1. It is suitable for grinding and crushing of food and drug composition analysis and detection.

2. It is suitable for grinding and crushing various plant tissues (roots, stems, leaves, flowers, fruits, seeds, etc.), fungi, bacteria and other samples;

3. Suitable for grinding and crushing various animal tissues including brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph node, muscle, bone and other samples;

3D cryogenic sample grinder product features:

1. Flexible parameters: controlled by micro-processing technology, various kits can be customized, 5.7-inch color touch screen, simple and convenient program setting (99 programs can be saved)

2. Good stability: The unique fastening mechanism makes it easier to fix the sample tube. The program calls are fast, and the running noise is less than or equal to 54db.

3. Professional and efficient: complete the sample fragmentation and lysis time period, avoid nucleic acid degradation and protein denaturation, and ensure the integrity of the extracted nucleic acid or protein. The patented design of low-speed and ultra-long continuous operation function (up to 30min) is suitable for cloning and sequencing of whole genes.

4. Integrated preparation: the unique grinding, freezing and centrifugation functions can effectively prevent the reduction of the biological activity of the sample caused by heat. The centrifugation function of up to 6000rpm omits a lot of complicated transfer operations, and it can also be used as a low temperature centrifuge alone.

5. Zero contamination of samples: The operation process is in a fully enclosed state to avoid cross-contamination between samples and external contamination.

6. High safety and easy maintenance: using a brushless variable frequency motor, no carbon particles will be generated, and there is no need to replace the carbon brush. Long service life, no wearing parts, all stainless steel inner cavity, more convenient cleaning and disinfection, and no need for auxiliary treatment of dangerous materials such as liquid nitrogen.
