Filtration Membrane Discs
MilliporeSigma™ Nylon Net Filters, 10 μm
Hydrophilic nylon membrane
Cytiva Whatman™ Type WCN Cellulose Nitrate Membranes
Recommended for majority of routine applications, this membrane is manufactured under strictly controlled conditions. Whatman™ Type WCN Cellulose Nitrate Membranes narrow pore size distribution for improved surface capture and analysis.
Cytiva Whatman™ WTP Range PTFE Membranes
Suited for applications involving aggressive organic solvents, strong acids, and alkalis due to being chemically stable and inert. Whatman™ WTP Range PTFE Membranes are particularly suitable for preparing samples for HPLC analysis, air and gas sterilization.
Cytiva Whatman™ PTFE Membrane Circles
Provides clarification of corrosives, solvents, and aggressive fluids. Whatman™ PTFE Membrane Circles are particularly useful in HPLC analysis when solid particles can cause permanent damage to the column.
Sartorius Microsart™ @Filter 100 in Trays
Membrane filters suitable for use in the Microsart @Filter units
Sartorius Polyamide (Nylon) Membrane Filters
Recommended for particle-removing filtration of water, aqueous solutions and solvents for analytical determination. Sartorius Polyamide (Nylon) Membrane Filters are white, non-sterile filters without grids. Choose from two pore sizes in four diameters. Bulk packed for space and cost savings.
UltraSep™ 47 mm Polyethersulfone Disc
Constructed from a high-temperature polyethersulfone polymer that is acid and base resistant. Its strength and durability are advantageous during usage that involves aggressive handling or automated equipment. It's naturally hydrophilic w/o added wetting agents and has low extractables.
Spectrum™ Spectra Mesh™ Woven, Nylon Filters
Consist of individual strands woven into a mesh screen
GVS Poretics™ 90 mm Polycarbonate Disc
Made from a thin, microporous polycarbonate film material. It is ideally suited for use in blood assays and high-purity and general filtration. Though polycarbonate is hydrophobic, the membrane is treated with a wetting agent to make it hydrophilic.
MilliporeSigma™ Durapore™ Membrane Filters, 0.45 μm
Durapore™ Membrane Filters are recommended when maximum recovery is important.
Cytiva Whatman™ Polyester Drain Discs
Provides a flat surface to eliminate filter tearing or rupturing. Whatman™ Polyester Drain Discs are used to support membrane filters. They are available in a variety of diameters for use in a range of devices.
GVS PolySep™ Polypropylene Disc
Polypropylene filtration membranes are composed of pure polypropylene with absolute pore size ratings. These filters offer broad chemical compatibility allowing its use with aqueous and organic solvent samples.
GVS PCTE Filter Membranes: Plain Hydrophilic
Smooth, flat surface for even distribution in a single plane.
MilliporeSigma™ MF-Millipore™ Membrane Filter, 0.8 μm
Mixed cellulose esters (MCE) membrane, hydrophilic
MilliporeSigma™ MF-Millipore™ Membrane Filter, 0.45 μm, Gridded
Mixed cellulose esters (MCE) membrane, hydrophilic
