Disc & sheet membranes

Disc & sheet membranes are the flat filtration media that laboratories load into holders, funnels and manifolds for particle retention, sterile filtration and sample clarification. Analytical, environmental and microbiology laboratories use disc and sheet membranes daily.

The 1,030 GVS listings are organised by polymer and format. Disc membranes are available in PES, PTFE, PVDF, nylon, polypropylene, mixed cellulose ester, polycarbonate track-etched, cellulose acetate and regenerated cellulose, with sheet membranes in MCE, nylon, PCTE, PETE and PVDF. Filter paper, drain discs, lint-free blotting paper and R-F reaction folders complete the range.

Choose the polymer first for solvent compatibility and wettability, then the pore size for the particles or organisms to retain, and finally the diameter to suit your holder. Lancetech Limited supplies these GVS membranes to UK laboratories and can quote on bulk or non-standard sizes.
