Pcte Sheet Membrane

PCTE sheet membranes are polycarbonate track-etched filters supplied as small rectangular sheets rather than discs. Laboratories building custom holders, flow cells or particle sampling devices use a PCTE sheet membrane when a precise cut-to-size format is needed.

Seven GVS listings share a 25 x 80 mm format in packs of 100, with pore sizes of 3.0 µm, 5.0 µm and 12.0 µm. Several are PVPF grades, and the 5.0 µm size is offered both with and without that treatment.

Select the pore size by the particles or cells to be retained on the surface, then decide whether the PVPF version suits your wettability requirement. Where a disc would do, the PCTE disc membrane section offers the same polymer in round formats. Lancetech Limited can quote other sheet sizes from GVS.
