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.

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.

Recommended when maximum recovery is important

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