Pall Capsule Filter KleenPak SUPOR EKV Membrane 0.2 um

Pall KA1EKVP6G KleenPak™ Capsule Filter (Supor® EKV, 0.2 µm, Gamma-Compatible)

The Pall KA1EKVP6G is a high-capacity, sterilizing-grade capsule filter designed for the rapid and secure filtration of biopharmaceutical fluids. Utilizing Pall’s proprietary Supor® EKV technology, this filter features an asymmetric double-layer PES membrane (0.2 µm rated) that provides exceptional flow rates and superior total throughput compared to standard symmetric membranes. The built-in 0.65 µm pre-filter layer protects the final 0.2 µm membrane from premature fouling, making it particularly effective for nutrient-rich cell culture media, complex buffers, and biological intermediates. As a "G" series model, this capsule is constructed from materials validated for gamma-irradiation, ensuring mechanical and chemical integrity when integrated into single-use manifolds.

Technical Performance and Design

• Asymmetric PES Membrane: The unique double-layer structure (0.65 µm over 0.2 µm) allows for high-capacity dirt loading and faster processing times, reducing the overall footprint required for large-volume filtration.

• Sterilizing-Grade Retention: Validated for the absolute removal of Brevundimonas diminuta (ATCC 19146) with a typical Titer Reduction Value (TRV) of >10⁷ per cm² of effective filtration area.

• Gamma-Compatible Housing: Manufactured from robust, high-purity polypropylene materials that maintain their structural integrity and low-extractable profile after exposure to standard gamma sterilization doses (up to 50 kGy).

• KleenPak™ Capsule Format: A self-contained, compact design that minimizes hold-up volume and eliminates the need for stainless steel housings, reducing cleaning validation requirements and capital expenditure.
