Mixed Cellulose Ester (MCE) Membrane

MCE filters are composed of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provide the fastest flow rates and highest throughput available in membrane filter. Because they are biologically inert, MCE filters are ideal for a wide range of clarification, sterilisation, and analytical applications such as microbiological analysis, clarification or  of aqueous solutions, industrial hygiene applications and particulate-matter analysis.

For gravimetric analysis using ashing techniques, MCE filters yield a residue of less than 0.045% of their initial weight. They are hydrophilic with a noncytotoxic wetting agent extractable level of less than 4% of their weight.

MCE filters are available in eight pore sizes ranging from 0.1µm to 8.0µm. Standard disc diameters are available from 13mm to 293mm in white or black with plain or gridded surfaces. These filters are autoclavable at 121°C (250°F) for 20 minutes.
