PureFlow Sterilizing Filter - 4pcs. – Witec AG

PureFlow™: Accelerate Asepsis. Maximize Throughput.

The Jet Biofil PureFlow™ Capsule Sterilizing Filters are the ready-to-use, high-performance solution engineered for critical liquid filtration in biopharmaceutical and life science applications. Designed to replace slow and inefficient traditional methods, the PureFlow™ system ensures maximum productivity from R&D through process scale-up.

• Premium Double-Layer PES Membrane: Built with hydrophilic, asymmetric Polyethersulfone (PES) membranes (typically 0.45µm + 0.22µm), the dual-layer structure provides exceptional dirt-holding capacity, preventing early-stage clogging and extending filter life.
• Guaranteed Aseptic Filtration: Achieves reliable and sharp retention of bacteria and particulates, making it the ideal choice for bioburden control and the sterilization of cell culture media, buffer solutions, reagents, and final drug products.
• Optimized Flow & Throughput: The superior membrane chemistry and integrated capsule design deliver excellent flow rates and high throughput, significantly boosting your bioprocess efficiency and minimizing downtime.
• Broad Compatibility: Constructed with robust, USP Class VI compliant materials (Polypropylene housing), the PureFlow™ capsule offers excellent chemical compatibility (pH 1-14) and ultra-low extractables, protecting the integrity of your sensitive fluids.
• Scale-Up Ready: Available in multiple sizes and connectivity options (Hose Barb, Sanitary Flange), enabling seamless and linear scale-up from laboratory batches to full process-scale bioproduction.
