MCE Membrane Filters, 0.22 Micron, 47mm, Sterile, Individual Pack

Nitrocellulose Mixed Ester (MCE) Membrane Filters, Sterile, Individual Pack, 47mm, 0.22 Micron

Advantec sterile, white Mixed Cellulose Ester (MCE) membranes--a versatile mixture of cellulose nitrate and cellulose acetate fibers--are general purpose filters with high recovery rates, high porosity, and superior flow rates. These pre-sterilised filters are suited for single use in many microbiological applications, including the examination of water, wastewater, pharmaceuticals, food, and beverages.

Hydrophilic MCE membranes utilize a mixture of cellulose nitrate/acetate fibers to deliver superior flow rates, precise pores, and high protein binding capacity; ideal for particle monitoring, diagnostic kit manufacturing, and microbiology applications.

Key Features

• Hydrophilic membrane with high protein binding
• Uniform pore structure and consistent thickness
• Superior flow rates and precise pore size
• Gridded and plain options available

MCE Filters in Microbiological Applications

Many microbiological techniques include colony counting after incubation as the standard method of quantification. Gridded filters have clearly defined grid lines spaced at 3.1 mm intervals. The special ink used is nontoxic and completely free from bacterial growth inhibitors. White gridded disks are designed for the recovery and retention of E. Coli bacteria in water/waste-water analysis as well as other microbiological tests. Black mixed cellulose esters(MCE) are available plain for automatic colony counting applications, as well as gridded to assist in manual counting procedures. Black MCE membranes provide contrast between residue or cell colors and the filter without having to counter-stain the membrane.
