MCE Membrane Filter


Microlab® mixed cellulose ester (MCE) membrane filters are composed of cellulose acetate and cellulose nitrate. lt’s one of the most widely used membranes in analytical and research applications. MCE membrane filter is characterized by smoother and more uniform surface than pure nitrocellulose(NC)Membrane filter. Also, the color contrast provided by the filter surface,facilitates particle detection and minimizes eye fatigue. Microlab® also supplies sterile gridded Membrane Filters with or without adsorbent pads.
