Filtration Membrane Discs
Cytiva™ Whatman™ Microplus MP31 Nitrocellulose Filtration Membranes, with Grid
Whatman™ MicroPlus MP31 Filtration Membranes are recommended for most routine applications and are manufactured under strictly controlled conditions. Supplied as 135 mm x 240 mm sheets with imprinted grid pattern (white lines on black) to aid particle counting.
Cytiva™ Whatman™ RC55 Regenerated Cellulose (Cellulose Acetate) Filtration Membranes
Whatman™ RC55 Regenerated Cellulose Filtration Membranes provide broad chemical compatibility and can be used with aqueous solutions or organic solvents. With low extractable and low binding properties they are ideal for sample preparation/mobile filtration in HPLC and with protein-containing solutions.
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 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 Microsart™ @Filter 250 in Bags
Membrane filters suitable for use in the Microsart @Filter units
Sartorius Regenerated cellulose (RC) Membrane Filters
These solvent-resistant, hydrophilic membrane filters are excellently suited for particle removal from solvents.
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.
