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 1020 cm² LP Series media are designed for intermediate scale-up studies and lab scale protein production.
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.
