In the seed inspection, many inspectors think that the sample processing of seeds is a rather troublesome process. For example, traditional seed grinding uses manual grinding, which is not only inefficient, but also has long grinding time and poor grinding results. If the seed sample is not handled well, it will directly affect the final test results. Therefore, in order to meet the high efficiency and high precision requirements of modern seed testing, seed sample processing has also become a new choice - high-throughput tissue grinding instrument . The use of a high-flux tissue grinder, which provides excellent grinding results, can be used as a substitute for manual grinding, greatly reducing sample grinding time, and can be used to deal with large batches of seed samples.
In general, the characteristics of seed samples should be handled, each sample alone, the use of appliances and consumables will not cross-contamination; both can be fully released, but also reduce degradation as much as possible, to retain the biological activity of macromolecules; reduce the chemical composition and The intervention of the enzyme does not affect the follow-up test; it is simple and efficient, handling multiple samples at the same time. The high-flux tissue grinder fully meets the above requirements for seed sample processing. At the same time, the high-throughput tissue grinder also has other superior performance, which can help the development of seed inspection.
Taking rice seed sample processing as an example, in order to extract nucleic acids more efficiently and quickly, we used a high-throughput tissue grinder in our experiments. In the first step, the XX ml special grinding tank and XX mm grinding ball are cleaned with XXX% ethanol and sterilized. The second is to take the appropriate amount of rice seeds to be ground into the grinding tank, and XX XXX mm grinding is added. The bead is covered with a lid; take liquid nitrogen XXX ml in the foam box, place the rice seed grinding tank in liquid nitrogen and freeze for XX minutes; place the grinding jar into the grinding instrument; fourth, set XXXhz, XXXs, Start the instrument until the end of the grinding process. In a few simple steps, the desired seed sample can be obtained for further inspection and analysis.
