Pall Capsule Filter Mini Profile 3 um 90 cm2 9/16 in. Barb

Pall 12071 Mini Profile Star Capsule Filter (Profile Star Media, 3 µm)

The Pall 12071 is a high-capacity Mini Profile™ Star capsule filter engineered for the efficient clarification of biological and chemical fluids. Featuring Pall’s absolute-rated Profile Star pleated depth media, this capsule provides a significant 90 cm² filtration area, which is double the surface area of standard depth capsules in this series. The pleated geometry combined with a continuously graded pore structure ensures high dirt-holding capacity and superior gel removal, making it an ideal choice for the protection of downstream membrane filters. Housed in a robust all-polypropylene assembly with 9/16-inch hose barb connections, the 12071 is designed for reliability in pilot-scale bioprocessing, reagent manufacturing, and laboratory-scale filtration workflows.

Technical Performance and Design

• High-Area Pleated Depth Media: The pleated Star geometry provides 90 cm² of effective filtration area, significantly reducing the flux (flow per unit area). This prevents premature pressure buildup and extends the life of the filter in high-solids applications.

• Absolute Removal Rating: Calibrated for 99.98% efficiency (Beta 5000) at 3 µm, providing the high level of security required for critical pre-filtration and clarification steps.

• Profile Star Graded Density: The media features a tapered pore structure that narrows toward the downstream side, allowing the outer layers to act as pre-filters for the inner layers, maximizing the use of the entire pleated matrix.

• Large-Bore 9/16" Connections: Features heavy-duty 9/16 in. (14.2 mm) hose barbs, which facilitate high flow rates and provide a secure, leak-proof connection with standard laboratory and industrial tubing.

Key Benefits & Applications

• Critical Pre-filtration: Ideally suited to protect expensive 0.2 µm and 0.45 µm sterilizing-grade membranes from premature fouling by larger aggregates, lipids, and cellular debris.

• Viscous Fluid Clarification: Optimized for handling oils, viscous reagents, and concentrated protein solutions where standard filters suffer from rapid clogging.

• Pilot-Scale Processing: The high-area pleated design allows for fast batch processing in biopharmaceutical R&D and diagnostic kit manufacturing.

• Chemical Compatibility: The 100% polypropylene construction provides broad resistance to many acids, bases, and organic solvents, ensuring low extractables and high purity.
