Supor 100Membrane Disc Filters, 0.1um - 25mm, Plain, 100/Pk SKU: 60309

Supor (PES) Membrane Filters - 60309

The Pall 60309 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. Asymmetric polyethersulfone construction places the tightest pore layer at the upstream membrane surface, maximizing retention efficiency while the open substructure sustains flow. In turn, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.
• 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.
• Temperature rating of 55°C provides the thermal headroom required for warm sample processing, heated media preparation, and elevated-temperature analytical methods.
• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.

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. In response, 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.
