Syringe Filters, Whatman Puradisc™ PTFE (Teflon), Sterile and Non-sterile
Overview
Whatman Puradisc PTFE (Teflon) syringe filters have housings produced from pigment-free polypropylene or polycarbonate, with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated). Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows a sample to be accurately dispensed into a micro-vial, eliminating air lock.
Because of the high chemical resistance PTFE is the membrane of choice for applications that include esterification of air or gas samples, HPLC solvents, filtration of aggressive solvents, sampling of aerosols, venting air, or protecting vacuum pumps.
Available in a wide range of pore sizes and diameters: pore sizes 0.20 and 0.45 µm (Puradisc 4, diameter 4 mm)), 0.1, 0.2, 0.45, 1.0, and 5.0 µm (Puradisc 13, diameter 13 mm), 0.1, 0.2, 0.45, and 1.0 µm (Puradisc 25, diameter 25 mm) and 0.2 µm (Puradisc 30, diameter 30 mm).
