Supor Membrane, 0.8um, 47mm, White, Gridded, Gamma Irradiated, Bulk w/ Parchment Separators, 200/Pk SKU: 65472

Supor (PES) Membrane Filters - 65472

The Pall 65472 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. Furthermore, asymmetric polyethersulfone construction places the tightest pore layer at the upstream membrane surface, maximizing retention efficiency while the open substructure sustains flow. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Rated for continuous operation at temperatures reaching 55°C, enabling filtration of heated solvents and process fluids without material compromise.
• Bulk format reduces per-unit packaging waste and cost, appropriate for routine particulate removal and clarification where aseptic handling is not specified.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Consistent lot-to-lot performance supports standardized filtration protocols, reducing the revalidation burden when transitioning between production lots.
• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.

When your analytical method specifies membrane filtration as a sample preparation step, the retention characteristics and extractable profiles documented above allow you to meet method requirements without additional qualification work. Under these conditions, the chemical compatibility range documented for this device allows you to verify suitability for your specific sample matrix before processing, avoiding the mid-filtration failures that waste both sample and time. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
