Purpose Of Filter Tip

The role of the tip filter:

Because the tip filter element is a disposable filter tip, its major function is to prevent cross-contamination: Unlike other filter types that contain additives that can inhibit enzymatic reactions, the filtered pipette tips supplied by Bunsen are made of Made of pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being sucked into the pipette body.

　　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. 

The filter tip also prevents the sample from entering the pipette and causing damage to the pipette during pipetting.

　　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.
