When to use filter tips for pipettes?
The pipette is a test instrument in biological research, and the number of its accessories tips used in the test is also very large. The tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and wide temperature range). However, with polypropylene, the quality can vary widely: high-quality filter tips are generally made of natural polypropylene, while cheap pipette tips are likely to be made of recycled polypropylene plastic (in this case Next, we can say that its main ingredient is polypropylene).
The function of the suction filter:
Since the tip filter is a disposable filter tip, the major role in the use process is to prevent cross contamination: Unlike other filter types that contain additives that can inhibit enzymatic reactions, the filtered tips supplied by Bunsen Made of pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being drawn into the pipette.
The filter of the tip cartridge is machine loaded to ensure complete uninterruption during the manufacturing and packaging process. They are certified free of RNase, DNase, DNA and pyrogen contamination. In addition, all universal filter tips are pre-sterilized by radiation after packaging for enhanced protection of biological samples.
The use of filter tips can be used to prevent the pipette from being damaged by the sample and greatly improve the service life of the pipette.
When should filter tips be used?
It is necessary to use filter tips in all molecular biology applications that are sensitive to pollution. Filter tips help reduce the possibility of smoke build-up, prevent aerosol contamination, and then achieve the goal of protecting pipette shafts from cross-contamination. Additionally, the filter barrier prevents sample carryover from the pipette, which in turn prevents PCR contamination.
The filter tip also prevents the sample from entering the interior of the pipette during pipetting, resulting in pipette damage.
Why is it necessary to use a tip filter for virus detection?
The virus is contagious. If the filter tip is not used to block the virus in the sample during the virus detection process, the virus will be transmitted through the pipette;
Depending on the test samples, filter tips can be contaminated by tissue samples during pipetting.
