Description
Technical field
The utility model relates to the liquid nitrogen grinding device technique field used in a kind of physiology, biochemistry, molecular biology, especially relates to a kind of liquid nitrogen grinding system.
Background technology
In the various physiology of modern life science, Food Science and environmental science, biochemistry or molecular biological research, often need fragmentation pre-treatment test specimen being carried out to physics, as the extraction of RNA/DNA, the separation of protein, mineral nutrient element (Na
+, K
+, PO
3 2-, Ca
2+deng) containing the analysis etc. of the mensuration of quantitative analysis, soluble sugar content, the analysis of soluble amino acid, the mensuration of chlorophyll content and various metabolic enzyme activity (as catalase, superoxide dismutase, glutathione reductase etc.), these test specimens comprise plant, animal or soil etc.And the quality of sample broke process directly can affect the accuracy of follow-up test result, as in aging research to the detection of Unit Weight tissue sample RNA or DNA content, if tissue grinder is insufficient, then detected value will be less than normal.Equally, the measurement of other physiology, biochemistry, molecular indexes also can because historrhexis is insufficient and then affect the accuracy of result of the test.In addition, some test also requires to grind under ice bath or ultralow temperature situation, as the mensuration of enzymatic activity and the extraction of RNA.Current, for the solution of various test requirements document to sample broke be: 1. utilize pottery or glass mortar tissue abrasion or grinding limit, limit under condition of ice bath to add liquid nitrogen to maintain ultralow temperature, then ground tissue solution or powder transfer are carried out follow-up test step to centrifuge tube or test tube; 2. special plant equipment such as tissue grinder instrument is utilized to grind, point normal temperature type and ultralow temperature type.Its shortcoming is: 1. for traditional mortar, and when test specimen process number is larger, grinding and transfer all need consuming time, and inefficiency; And all need carefully to clean mortar before and after test, dry, sterilizing, even high-temperature baking (toasting more than 6h as needed 180 DEG C when RNA extracts), therefore expense people requires great effort time-consuming.In addition, as extracted RNA or DNA, when liquid nitrogen is added in ultralow temperature grinding repeatedly, due to strong liquid-nitrogen boiling, ground powder of organizing can be caused everywhere to splash, very easily because operating experience deficiency can cause the cross pollution between sample and sample, and then cause test failure.2. for the plant equipment of special grinding, it involves great expense, and the laboratory of not all or scientific research personnel all can have enough funds to buy, and for the few sample of number, special-purpose machinery grinding needs to expend more liquid nitrogen, does not calculate economically.In the scientific research field of modern forward position, each scientific research project comprises numerous experimental procedures, and completing of each experimental procedure needs at substantial time and painstaking effort; Therefore, cause whole scientific research project period planning to baffle because some annelet goes wrong or make whole previous experiments all that has been achieved is spoiled to be unacceptable.
