MilliporeSigma™ Isopore™ Membrane Filters, 0.1 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™ Cyclopore PC Polycarbonate Membrane Filters
Microporous membranes featuring sharp cut-off and reproducible lab microfiltration characteristics of track-etched membrane filters
Sartorius Cellulose Acetate Membrane Filter
Cellulose acetate membrane filters with 293 mm diameter combine thermal stability with exceptionally low adsorption characteristics.
Sartorius Cellulose Nitrate Membrane Filter
Cellulose nitrate membrane filters with 142 mm diameters are hydrophilic, have high flow rates thanks to their symmetrical structure and are compatible with aqueous solutions, hydrocarbons and several other organic solvents.
Sartorius Nongridded Sterile Cellulose Membrane Filters
Ensure quality control in routine microbiological filtering. Sartorius Nongridded Sterile Cellulose Membrane Filters are single-packed membranes used for colony counting, particle testing, microscopy and sterility testing. Choose between cellulose acetate or cellulose nitrate membranes in a variety of pore sizes.
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.
Sartorius Environmental Air Monitoring Gelatin Membranes
Collect airborne microbes and viruses. Sartorius Environmental Air Monitoring Gelatin Membranes guarantee reliable and accurate results. They are sterile and water soluble with a high retention rate. Choose from a range of sizes in single-wrapped disposable filters with holders or packs of filter disks.
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.
Cytiva Whatman™ Mixed Cellulose Ester Membranes
Color contrast helps easier particle detection.
Cytiva Whatman™ 47 mm 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.
