Pall Introduces Depth Filter Capsule System

The Pall Stax single-use depth filter platform helps to reduce labor time and eliminates equipment cleaning expenses and cleaning validation requirements incurred by biopharmaceutical manufacturers with traditional plate and frame depth filtration systems.

The platform can be anchored to the floor or placed on casters for easy mobility. Its compact vertical design (up to six feet high) reduces floor space requirements.

The system is comprised of interchangeable single-use depth filter capsules housed in a stainless steel chassis that can be managed easily by a single operator. Scalable in size and for performance to meet lab, pilot and process requirements, the capsule sizes permit mix-and-match incremental increases in filter area (0.25 sq m to 2.0 sq m effective filtration area) throughout the modular design. The system offers two manifold configurations – bottom in/top out and bottom in/bottom out.

With three chassis sizes and a wide selection of depth filter media, the platform offers flexibility to operate the capsule stack in a serial flow mode. Two grades of filter media capsules can operate in series within one chassis. Multiple chassis can operate in a parallel configuration.

The platform uses the company’s cellulose-based Seitz high performance depth filter media and its second generation Supradisc II dual drainage plate modular design to encapsulate the media.
