The Zeta Plus™ Encapsulated System retains the lenticular filter design and vertical flow path that are characteristics of traditional depth filtration systems, helping ensure consistent performance from bench scale to production scale. The scale-up filter capsules with 170 cm² LA series media are designed for intermediate scale-up studies and lab scale protein production.
3M™ Zeta Plus™ LA Series Low Aluminium Filter Media is designed to provide low levels of metallic extractables, especially aluminium. This premium grade low aluminium filter media is ideally suited for parenteral, blood fraction, dextrose, bioprocess solutions and infant food/formula applications. The Zeta Plus LA Series are constructed from materials listed in 21 CFR. Stringent quality controls ensure maximum product performance for each production lot.
The Zeta Plus LA Series filter media exhibits a positive electrokinetic charge that enhances filtration efficiency when compared to other depth filters. When used as a prefilter, the high contaminant holding capacity of Zeta Plus LA Series filter media prolongs final filter life.
