MCE Gridded Membrane Filter

Johnson Test Papers’ MCE Gridded Membrane is sterile-sealed filter, without protective paper in an individual package. We offer a complete range of mixed cellulose ester membranes, with a wide choice of pore sizes (from 0.22 to 1 μm) and diameters. The membranes are available with or without a grid pattern that are used in many microbiological techniques such as colony counting after incubation. There are clear advantages to these membrane filters including operating convenience, less risk of accidental membrane contamination, less care and skill required to aseptically separate membrane from packaging and a reduction in test time.

Johnson Test Papers' MCE Gridded membranes are composed of cellulose acetate and cellulose nitrate. The membrane offers a high degree of porosity of internal surface area for greater product adsorption. Mixed cellulose ester membranes are biologically inert and are one of the most widely used membranes in analytical and research applications. They are ideal for gravimetric analysis and are particularly suited for aqueous solutions. This membrane is also often used for contamination tests. They are naturally hydrophilic, biologically inert and offer good thermal stability up to 90 °C.

MCE Gridded membrane is characterised by a smoother and more uniform surface than the pure nitrocellulose (cellulose nitrate) membrane which facilitates particle detection and a high retention level.
