Supor 450Membrane Disc Filters, 0.45um - 25mm, Plain, 100/Pk SKU: 60172

Supor (PES) Membrane Filters - 60172

The Pall 60172 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Developed with critical workflows in mind, full pH compatibility from 1 to 14 allows Supor membranes to handle acidic mobile phases, neutral buffers, and alkaline cleaning solutions without performance degradation. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.
• Consistent lot-to-lot performance supports standardized filtration protocols, reducing the revalidation burden when transitioning between production lots.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.

Air monitoring and stack emissions sampling demand a filter medium that withstands the conditions at your collection point. The material properties above define that operating envelope. For this application, 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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
