Supor 450Membrane Disc Filters, 0.45um - 293mm, Tabbed, 25/Pk SKU: 60179

Supor (PES) Membrane Filters - 60179

Designed to deliver reproducibility and confidence across critical sample types, the Pall 60179 provides the filtration consistency that method validation demands. Low extractable levels ensure that Supor membranes contribute minimal background to filtered preparations used in sensitive cell culture and analytical applications. In sum, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• 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.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.
• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. In response, consistent manufacturing means the filtration performance you observe during initial evaluation repeats on every subsequent unit, supporting the reproducibility your quality system requires. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
