Abstract
This application discloses porous self-sealing media comprising a sintered mixture of an absorbent material and a thermoplastic. The self-sealing media block passage of organic solvents or organic solvents in aqueous mixtures, wherein the organic solvents are at concentrations greater than about 40%. The self-sealing media also block acidic solutions. The self-sealing media are useful in a variety of applications such as a pipette tip filter, in line filter, vent, non-mechanical check valve, safety valve, and suction canister.
