Porous Plastic Polyethylene Filter tips - POLYPOR™ are especially suited for working with PCR techniques, and fully meet the requirements for microbiology and radioisotope work. The integrated hydrophobic polyethylene filter serves as a barrier against aerosols formed during pipetting.
Filter tips from POLYPOR™ protect the pipette shafts from contamination, and thus lessen the risk of cross-contamination and faulty measuring results.
“Self-sealing” Porous Plastic Filter media in this invention are defined as porous media that allow air and gas to pass through when the media are dry and do not allow air, gas or solutions to pass through when the media contacts aqueous based or organic solvent-based liquid solutions, for example under suction forces or pressure. The suction forces are vacuum or negative pressures.
Use of these self-sealing media provides a safer environment for transfer of highly corrosive inorganic acids and organic acids
