Pall Life Sciences Introduces Stax Single-Use Depth Filter Capsule System For Demanding Biopharmaceutical Applications
The most flexible single-use depth filter capsule system for demanding pre-filtration and clarification processes in biopharmaceutical applications will be unveiled by Pall Life Sciences at INTERPHEX 2009, the world’s largest pharmaceutical conference and exhibition. Pall Life Sciences is a business of Pall Corporation (NYSE: PLL), a global leader in filtration, separation and purification. 
The new Pall Stax™ single-use depth filter platform helps reduce costly 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/two meters high) reduces floor space requirements.
The Pall Stax 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 (small-medium-large) permit mix-and-match incremental increases in filter area (0.25 m² to 2.0 m² 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 Pall Stax 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 new platform uses Pall’s cellulose-based Seitz® high performance depth filter media and its second generation Supradisc™ II dual drainage plate modular design to encapsulate the media, assuring high performance filtration and overall process stability. The unique cage-like structure of Supradisc II modules are fitted within the Stax capsules. Interlocking inside and outside separators support the depth filter media and eliminate the possibility of media ruptures from pressurization. These same separators serve as drainage plates that enable full access of feed solutions to the available filter area, and they also account for accurate and reliable utilization of the entire filter capacity.
