Hydrophobic membrane with laminated backing for easier handling

Polyethersulfone (PES) filters have a high internal porosity.

Protect the vacuum source during aspiration with this membrane filter. Integra Biosciences™ Hydrophobic Membrane Filters are designed for use with VACUSAFE Aspiration Systems.

Plain white polyethersulfone membranes provide ultrafast filtration for a variety of applications

Recommended when maximum recovery is important. Durapore™ PVDF Membranes: 0.45μ Pore Size provide high flow rates and throughput, low extractables, broad chemical compatibility and low protein binding. Available in diameters ranging from 13mm to 142mm.

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

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.

Ensure quality control in microbiological filtering. Sartorius™ Gridded Sterile Cellulose Nitrate Membrane Filters, 0.45μm are single-packed membranes with colored grids for colony counting, particle testing and microscopy. The 0.45μm pore size is made in accordance with ISO 7704. Choose from two diameters and quantities in a range of filter/grid color combinations.

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

Ideal for filtering or sterilizing nonprotein-containing biological solutions.

Carry out particualte and microbial analysis with these filter membranes. Available in various forms for water quality work, cold sterilization or sample clean up.
