Supor 800 Membrane Disc Filters, 0.8um - 142mm, No Tab, 25/Pk SKU: 66555

Supor (PES) Membrane Filters - 66555

Designed to deliver reproducibility and confidence across critical sample types, the Pall 66555 provides the filtration consistency that method validation demands. Equally important, ultra-low protein binding surface chemistry minimizes adsorptive losses during filtration of dilute protein solutions, growth factor preparations, and cell culture supplements. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Consistent lot-to-lot performance supports standardized filtration protocols, reducing the revalidation burden when transitioning between production lots.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.

Environmental monitoring programs where sample-to-sample comparability determines trend validity benefit directly from the lot-level consistency of these membranes, removing the filter as a variable in your long-term data sets. To address this, complete specification documentation for this device supports the traceability requirements of your quality system, providing the recorded evidence of consumable performance that auditors and method reviewers expect to see. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
