Supor 450Membrane Disc Filters, 0.45um - 47mm, Plain, 100/Pk SKU: 60173

Supor (PES) Membrane Filters - 60173

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Furthermore, high flow rate performance reduces processing time in vacuum filtration setups, making Supor the preferred membrane for laboratories filtering multiple liters per session. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• 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.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• 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.

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. Meeting this challenge, the documented retention specifications of this device ensure that your filtrate meets the particulate cleanliness requirements of your downstream analytical or process step without additional verification. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
