GE Healthcare Whatman™ 90mm Nuclepore™ Polycarbonate Track-Etched Membranes

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.

Sartorius Stedim Biotech™ Polyethersulfone (PES) Membrane Filters

General purpose membrane that provides excellent performance with most solutions when retentate recovery is of primary importance.

GE Healthcare 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.

GE Healthcare 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.

GE Healthcare Whatman™ Nuclepore™ Black Polycarbonate Membranes

Reduces background fluorescence in support of epifluorescence microscopy. Whatman™ Nuclepore™ Black Polycarbonate Membrane Filters improve visibility and help to distinguish microorganisms from other particulates.

Merck Millipore Durapore™ PVDF Membrane Filters: Hydrophobic

Recommended when maximum recovery is important

Merck Millipore Durapore™ Membrane Filter

Strength, flexibility, and broad chemical compatibility for critical biological separations

Sartorius™ Microsart™ @Filter 100 in Bags

Membrane filters suitable for use in the Microsart @Filter units

GE Healthcare Whatman™ Anodisc™ Filter Membranes

Constructed with precision pore structure and narrow pore size distribution. Whatman™ Anodisc™ Filter Membranes ensure a high level of particle removal efficiency. Captures microorganisms and particulates on the surface of the membrane for subsequent analysis.

Sartorius™ Cellulose Acetate Membrane Filters

Combines high flow rates and thermal stability with very low adsorption characteristics. Sartorius™ Cellulose Acetate Membrane Filters are excellently suited for use in pressure filtration devices. Non-sterile filters in a variety of diameters and pore sizes are bulk-packed to save money and space.

GE Healthcare Whatman™ 47mm Nuclepore™ Polycarbonate Track-Etched Membranes

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 47mm Nuclepore™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.
