过滤尖端的目的

提示过滤器的作用：

由于尖端过滤器元件是一次性过滤器尖端，其主要功能是防止交叉污染：与含有可以抑制酶促反应的添加剂的其他过滤器类型不同，Bunsen提供的过滤的移液管尖端由纯原始烧结聚乙烯制成。。疏水性聚乙烯颗粒防止气溶胶和液体被吸入移液管体中。

　　The filter of the tip filter element is machine-loaded to ensure that it is completely unaffected during the manufacturing and packaging process. They are certified to be free of RNase, DNase, DNA and pyrogen contamination. In addition, all filters are pre-sterilized by radiation after packaging to enhance the protection of biological samples.

　　The use of filter tips can be used to prevent the pipette from being damaged by the sample and greatly increase the service life of the pipette.

　 When to use the tip filter:

　　When to use the tip filter tip? Filtered pipette tips must be used in all molecular biology applications that are sensitive to contamination. The filter tip helps reduce the possibility of smoke formation, prevents aerosol contamination, and thus protects the pipette shaft from cross-contamination. In addition, the filter barrier prevents the sample from being carried away from the pipette, thereby preventing PCR contamination.

过滤器尖端还防止样品进入移液器并在移液期间引起移液管损坏。

　Why a suction tip filter must be used to detect the virus?

　　The virus is contagious. If the filter tip is not used to isolate the virus in the sample during the virus detection process, it will cause the virus to be transmitted through the pipette;

　　The difference between the test samples, the filter tip can organize the cross-contamination of the sample during the pipetting process.
