NY Disc Membrane

An NY disc membrane is a nylon filter disc commonly used with aqueous and organic solvents, which makes it a frequent choice for mobile phase and sample filtration in HPLC laboratories. Chemists reach for nylon disc membranes when one membrane must cope with mixed solvents.

Nine GVS listings cover 13 mm discs at 0.8 µm and 47 mm discs at 1.0 µm in packs of 100, a 100 mm disc at 0.22 µm in packs of 25, and a 137 mm HY-grade disc at 0.45 µm in packs of 50, among other sizes.

Select 0.22 µm or 0.45 µm for clarifying mobile phases and samples before chromatography, and the coarser 0.8 µm and 1.0 µm grades for prefiltration. Match the diameter to your filter holder or funnel. Lancetech Limited supplies GVS nylon membranes and quotes on request.
