The EZP system from 3M incorporates two product lines, a small holder (Model No. 16EZA) for use at pilot or small scale protein production and a large holder (Model No. 16EZB) with pivot action which can accommodate up to 11.2 m² of filter media, making it ideal for large production scale protein purification. Both models consist of a filter holder, a set of manifold plates and filter capsules available in 0.23 m² and 1.6 m² configurations. Lynne Deakin, field applications specialist of 3M’s CUNO Filtration business said of the EZP: “It has been developed in response to requirements for a disposable depth filtration solution that allows loading and unloading at waist height so operators don’t have to lift capsules above their heads and risk exposure to fluid spills when handling used capsules.”
The EZP system utilises Zeta Plus EXT media which extends depth filtration capacity and improves protection of downstream membranes. Applications for Zeta Plus EXT Series filter media include removing impurities such as host cell proteins, viruses, DNA, protein aggregates and endotoxin.
