Introduction：Shanghai Jingxin Frozen Bone and Teeth Pulverizer is mainly used in DNA laboratory to detect the pretreatment of bones and teeth or the fields where teeth and bones need to be pulverized.
At present, the existing pulverizing grinders are all pulverized by blades, and the structure is relatively complex, and the effect of grinding and pulverizing bones is not good. When grinding, the operation is cumbersome, and the blades are severely worn or easily bent or broken. , due to the relatively high hardness of the bone, it is easy to damage the machine, and even pop up and hurt the operator, which has the problem of poor safety in use; and the high temperature generated during grinding will degrade the cells and tissues in the bone, resulting in poor inspection results. , and liquid nitrogen and other cooling should be used, otherwise, high temperature is likely to occur during the crushing process, resulting in the loss of biological information, making it impossible to obtain the relevant information of the victim, and liquid nitrogen and other coolants are likely to cause injuries to operators, posing safety hazards, and equipment. Expensive and less stable to use.
Shanghai Jingxin Frozen Bone and Teeth Pulverizer is mainly used in DNA laboratory to detect the pretreatment of bones and teeth or the fields where teeth and bones need to be pulverized. The crushing process adopts a one-time or re-sterilizable crushing tank, which can prevent environmental pollution and cross-contamination, and has high practical value. Cryogenic grinding of samples can effectively inhibit nucleic acid degradation, retain protein activity, and easily handle samples that are difficult to handle by conventional methods. The grinding effect is highly reproducible.
Product principle:
Use a scalpel to clean the bone surface layer and dirt and saw it into small pieces, clean the tooth surface, soak it in 5% (W/V) sodium hypochlorite solution for 15 minutes, discard the sodium hypochlorite solution, and rinse it with distilled water for 3 times to remove sodium hypochlorite. Soak in absolute ethanol for 15 min to remove residual water {5}, dry in a fume hood, and grind bone chips and teeth into bone powder and tooth powder with Shanghai Jingxin Frozen Bone and Teeth Grinder.
Put the sample and grinding ball into the grinder (with grinding jar or centrifuge tube/adapter), under the action of high frequency swing, the grinding ball collides and rubs back and forth in the grinder at high speed, and the sample can be completed in a very short time Grinding, crushing, mixing and cell wall breaking.
