Filtration Membrane Discs
Cytiva Whatman™ 0.45 μm Pore Size (ME 25) Mixed Cellulose Ester Membranes, White/Black Grid
Whatman™ (ME 25) Mixed Cellulose Ester Membranes, White/Black Grid are particularly effective in applications requiring higher flow rates and larger volume filtration. Supplied with clearly defined grid lines at regularly spaced intervals to assist in microbiological colony counting.
MilliporeSigma™ Nylon Net Filters, 1.2 μm
Hydrophilic nylon membrane
MilliporeSigma™ 13mm Membrane Filter
Biologically inert mixture of cellulose acetate and cellulose nitrate
Cytiva Whatman™ 90 mm 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 Microsart™ @Filter 250 in Bags
Membrane filters suitable for use in the Microsart @Filter units
Sartorius Microsart™ e.motion Membrane Filters
For colony counting, particle testing and microscopy. Specifically designed for use in the Microsart™ e.motion dispenser, the filters are individually sterile-sealed in a format packaged on a pleated band, without protective paper. Can also be used with Sartorius nutrient pad sets.
MilliporeSigma™ LCR Hydrophilized PTFE Membrane Filters
Filtration of aqueous fluids with no wetting
Cytiva GN Metricel™ Membrane Disc Filters

DWK Life Sciences DURAN™ Sintered Glass Filter discs
Non-fused edge
MilliporeSigma™ Isopore™ Membrane Filters, 0.6 μm
Use for analyses of airborne contaminants and other particles using optical or electron microscopy. Isopore™ Polycarbonate Membrane Filters have a smooth, glass-like surface for clearer sample observation. Available in a variety of pore sizes/flow rates, diameters and colors.
Cytiva Whatman™ ME 24 Plain Mixed Cellulose Ester Membranes
Enables the uptake of growth media to the bacterial colonies without chemically inhibiting their growth. Whatman™ ME 24 Plain Mixed Cellulose Ester Membranes are composed of cellulose acetate and cellulose nitrate, which provides a more uniform surface.
Cytiva Membra Clear Membrane
Mixed cellulose ester membranes
Sartorius Gridded Nonsterile Cellulose Nitrate Membrane Filters: 1.2μm Pore Size
The non-sterile membrane filters are made of cellulose nitrate (cellulose mixed ester), cellulose acetate or regenerated cellulose. They can be used for colony counting, particle testing and microscopy. Choose between gridded or non-gridded, membranes, either with or without hydrophobic edge.
