Pall Capsule Filter KleenPak SUPOR EKV Membrane 0.2 um

Pall KA2EKVP1G Kleenpak Capsule Filter – Supor EKV, 0.2 µm, Sanitary Flange

The Pall KA2EKVP1G is a highly efficient Kleenpak capsule filter engineered for the sterile filtration of biopharmaceutical fluids. Equipped with the industry-leading Supor EKV membrane, this capsule utilizes an asymmetric polyethersulfone (PES) construction with a built-in pre-filter layer to deliver exceptional flow rates and extended throughput. The "KA2" size offers a 750 cm² effective filtration area, making it ideal for processing intermediate batch volumes ranging from 3 liters to 120 liters. Outfitted with 1-1½ inch sanitary flange connections, this ready-to-use capsule seamlessly integrates into single-use manifolds and traditional stainless-steel piping, providing a reliable, sterilizing-grade barrier for buffers, cell culture media, and high-value active pharmaceutical ingredients.

Technical Performance and Design

• Asymmetric Membrane Technology: The Supor EKV membrane features a built-in asymmetric pre-filtration layer that tapers down to a 0.2 µm final rating. This prevents premature membrane fouling and dramatically increases total filter capacity.

• Ultra-Low Protein Binding: The hydrophilic PES membrane chemistry ensures minimal non-specific binding, maximizing the recovery of sensitive proteins, monoclonal antibodies (mAbs), and other vital biologicals.

• Sanitary Flange Connections: The P1 connection configuration features standard 1 to 1½ inch (25-38 mm) sanitary flanges (Tri-Clamp compatible) on both the inlet and outlet, ensuring secure, leak-free, and hygienic integration.

• Robust Single-Use Design: The compact Kleenpak housing eliminates the need for expensive filter housing cleaning and validation, reducing turnaround times and the risk of cross-contamination between batches.
