Whatman* Anodisc* Filter Membranes

Anodisc membrane filters consist of an Anopore* membrane disc, peripherally bonded to an annular polypropylene ring. Anopore is a unique, inorganic membrane, made of aluminum oxide, with a precise nondeformable honeycomb pore structure. Its narrow pore size distribution ensures extremely efficient removal of particles at the rated pore size. Low protein binding and hydrophilic. These filters are suitable for use in a wide range of specialized applications, including HPLC mobile phase filtration and degassing, bacterial analysis by epifluorescent light microscopy, ultra cleaning of solvents, gravimetric analysis and liposome extrusion. 75 psi 15 (vacuum) maximum operating pressure. 60 µm average membrane thickness. Porosity: 20 - 50%. Refractive index when wet with aqueous solution: 1.60. Not autoclavable.
