Supor 200 Membrane Disc Filters, 0.2um - 142mm, Tabbed, 25/Pk SKU: 60305

Supor (PES) Membrane Filters - 60305

Engineered for high retention efficiency and superior chemical stability, the Pall 60305 achieves reliable separation results across a broad range of analytical and preparative applications. Optimized for laboratory use, high flow rate performance reduces processing time in vacuum filtration setups, making Supor the preferred membrane for laboratories filtering multiple liters per session. As designed, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 55°C, supporting heated filtration protocols.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• 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.

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. With this in mind, rated flow specifications give you a reliable basis for estimating your filtration throughput, allowing you to plan batch sizes and processing schedules without the uncertainty that uncharacterized consumables introduce. 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.
