What is the function of a pipette tip with a filter element?

The filter core (mostly made of polypropylene with a pore size of 0.2-5μm) inside the pipette tip can block aerosols generated during pipetting (such as tiny droplets formed by sample evaporation), and at the same time prevent the liquid from flowing back into the pipette barrel when the liquid is drawn too quickly or pressed in reverse, thus avoiding corrosion of the precision components inside the pipette (such as the piston and sealing ring). Extend the service life of the instrument. Eliminate cross-contamination and ensure the accuracy of experimental results. The filter element can physically isolate different samples When transferring samples of different batches and types (such as nucleic acids, proteins, and microorganisms), the filter cartridge can prevent the residue (liquid or aerosol) of the previous sample from entering the pipette and contaminating the next sample. It is particularly suitable for experiments that are sensitive to contamination, such as PCR, nucleic acid extraction, and clinical testing, ensuring the repeatability of the results.Suitable for special samples, it enhances the stability of pipetting. For volatile, foam-prone or sticky samples (such as alcohol, DMSO, cell culture medium), the filter cartridge can reduce the risk of sample adhesion and reflux, while avoiding direct contact between the sample and the pipette, protecting the purity of the sample (for example, enzyme-free and pyrogen-free filter cartridge tips can prevent the samp |
