Supor Membrane, 0.2um, 47mm, Gridded, White, Gamma-Irradiated , Bulk w/ Parchment Separators, 200/Pk SKU: 66234

Supor (PES) Membrane Filters - 66234

Engineered for high retention efficiency and superior chemical stability, the Pall 66234 achieves reliable separation results across a broad range of analytical and preparative applications. Equally important, uniform pore size distribution across the membrane surface ensures consistent particle retention from center to edge, supporting reproducible analytical and preparative results. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.

Microbial enumeration methods require complete retention at rated pore size and a growth-supporting surface. The membrane specifications above confirm both requirements for your culture-based workflows. Consistent manufacturing means the filtration performance you observe during initial evaluation repeats on every subsequent unit, supporting the reproducibility your quality system requires. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
