Grid Marked Cellulose Nitrate Membrane Disc Filters 

Grid Marked cellulose nitrate membrane disc filters are primarily useful for water and product microbiology and the grid on the surface facilitates the counting of colonies. 

The filters are also produced in a facility with an ISO-9001: 2008 certified quality management system. 

Finally, validated for ASTM D 4200-82, a standard test method for evaluating the inhibitory effect of ink grids on membrane filters. 

Beschikbare micronages: 0.2μm, 0.45μm

Beschikbare diameters: 47mm, 50mm

The disc filters are also available in ‘reel form’. Offered in the form of a reel for use with automated systems. The main advantage here is that the diaphragm is dispensed automatically and that the chance of touching the diaphragm during peeling is minimised. These membrane reels are compatible with various membrane dispensers available on the market.
