More details



High pore density and narrow pore size distribution make it an extremely precise membrane


  • Extremely low protein binding minimizes sample loss


Aluminum oxide material. Consist of an Anopore® membrane disc, peripherally bonded to an annular polypropylene ring. Compatible with a wide range of organic chemicals, solvents and aqueous solutions, eliminating the need for multiple filter types. Sieve-like properties of Anopore® membrane enable microorganisms and particles to be retained on membrane surface for electron microscope examination. Virtually transparent when wet permitting examination by light microscopy without need to transfer the retained material. Wide solvent compatibility reduces the need to stock a variety of membranes in the laboratory.
