Thermo Scientific™ Nalgene™ Membrane and Prefilter Disks
Carry out particulate and microbial analysis with these filter membranes. Available in various forms for water quality work, cold sterilization or sample clean up.
Cytiva Whatman™ Mixed Cellulose Ester Membrane Filters
Whatman™ Mixed Cellulose Ester Membrane Filters are biologically inert and offers high degree of internal surface area for greater product adsorption.
Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters: 0.45μm
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.
Sartorius Cellulose Nitrate Membrane Filters
Combines uniform pore structure with high flow and adsorption rates. Sartorius Cellulose Nitrate Membrane Filters are excellently suited for diagnostic kits. Non-sterile, hydrophilic filters in a variety of diameters and pore sizes are bulk-packed to save money and space.
Cytiva 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.
Cytiva 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.
Cytiva Whatman™ Polyester Drain Discs
Provides a flat surface to eliminate filter tearing or rupturing. Whatman™ Polyester Drain Discs are used to support membrane filters. They are available in a variety of diameters for use in a range of devices.
