We developed the 3M™ Zeta Plus™ Encapsulated System Scale-Up Filter Capsules with M Series Media to provide economical small scale clarification of pharmaceutical, biological, bioprocess, and cosmetic fluids. Our depth filtration media is composed of inorganic filter aid, cellulose and a positively charged resin system that that pulls negatively charged contaminants from the fluid. 3M™ Zeta Plus™ M series filter products are a family of depth filter media which incorporates lipid-specific adsorbents for selective reduction of lipids, surfacta
The Zeta Plus LP series filter media are constructed with highly purified cellulose to minimize ß-glucan extractables and false positive LAL test results. The positive charge exhibited by the filter media results in increased particle reduction efficiency. The high contaminant capacity of the filter medium prolongs final filter life when LP media are used as a prefilter.
