Time is precious, mistakes are not an option - for you or for Alberts Filter. Throughout our entire membrane filters production process, we maintain only the strictest levels of quality control. Alberts Filter Mixed Cellulose Ester (MCE) membrane filter is composed of cellulose acetate and cellulose nitrate. Because the MCE membrane is biologically inert, it is one of the most widely used membranes in analytical and research applications. Gridded filters have clearly defined grid lines spaced at 3.1 mm intervals. The special ink used is non-toxic and completely free from bacterial growth inhibitors. Our gridded Mixed Cellulose Ester (MCE) membrane are ideal for colony counting and sterility testing. Sterile gridded MCE membranes are unsupported, naturally hydrophilic membranes.
