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.

Sartorius Cellulose Acetate Membrane Filters

Combines high flow rates and thermal stability with very low adsorption characteristics. Sartorius Cellulose Acetate Membrane Filters are excellently suited for use in pressure filtration devices. Non-sterile filters in a variety of diameters and pore sizes are bulk-packed to save money and space.

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™ 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.

Cytiva Whatman™ Nylon Membranes

Flexible and durable for easier handling. Cytiva Nylon Membranes are naturally hydrophilic, eliminating need for wetting agents and prewetting when filtering aqueous solutions.

Cytiva Whatman™ Nuclepore™ Hydrophilic Membrane

A highly defined pore size cutoff in the sub-micron range enables particle deformity measurements, and the capture of extremely small particles

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.

Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters: 0.2μm

Ensure quality control in routine microbiological filtering. Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.2μm are single-packed membranes with black grids for colony counting, particle testing and microscopy. The 0.2μm pore size is BCT validated. Choose from two diameters and packaging quantities.

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.

Cytiva Whatman™ Nuclepore Hydrophilic Membrane

Nuclepore track-etched hydrophilic membranes with highly defined pore size cutoff in sub-micron range
