Filtration Membrane Discs
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.
Sartorius Gridded Nonsterile Cellulose Nitrate Membrane Filters: 0.2μm 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.
MilliporeSigma™ Nylon Net Filters, 180 μm
Hydrophilic nylon membrane
MilliporeSigma™ S-Pak™ Sterile Membrane Filter Kit
Made from mixed esters of cellulose and have been optimized for MF method microbiological analysis of water or other liquids
MilliporeSigma™ Fluoropore™ Membrane Filters, 0.45 μm
Hydrophobic membrane with laminated backing for easier handling
DWK Life Sciences DURAN™ Sintered Glass Filter discs
Non-fused edge
MilliporeSigma™ MF-Millipore™ Membrane Filter, 0.025 μm
MF-Millipore™ Membrane Filter is a 13 mm diameter, mixed cellulose esters (MCE) membrane, hydrophilic.
Sartorius Cellulose Nitrate Membrane Filter
Cellulose nitrate membrane filters with 293 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.
Cytiva Whatman™ Sterile Mixed Cellulose Ester Gridded Membranes
Composed of cellulose acetate and cellulose nitrate.
MilliporeSigma™ Omnipore™ Membrane Filters, 0.45 μm
Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.
Cytiva Whatman™ 0.6 μm Pore Size (ME 26) Mixed Cellulose Ester Membranes, Plain
Whatman™ (ME 26) Mixed Cellulose Ester Membranes are particularly effective in applications requiring higher flow rates and larger volume filtration, including clarification or sterilization of aqueous solutions, particulate analysis and removal, air monitoring, and microbial analysis.
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.
MilliporeSigma™ Omnipore™ Membrane Filters, 0.45 μm
Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.
MilliporeSigma™ Fluoropore™ Membrane Filters, 5 μm
Hydrophobic membrane with laminated backing for easier handling
Cytiva Whatman™ Regenerated Cellulose Membranes: Grade RC 55
Consists of pure cellulose without any wetting agents.
