Pall
Supor 450Membrane Disc Filters, 0.45um - 90mm, Plain, 100/Pk SKU: 60206

Supor (PES) Membrane Filters - 60206

The Pall 60206 protects sensitive instrumentation and sample integrity by providing reliable particulate removal with minimal analyte adsorption or background interference. High flow rate performance reduces processing time in vacuum filtration setups, making Supor the preferred membrane for laboratories filtering multiple liters per session. Because of this, from raw polymer through final inspection, the manufacturing process is designed to ensure that every membrane disc meets the performance specifications of its grade designation.

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.
• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
• Consistent lot-to-lot performance supports standardized filtration protocols, reducing the revalidation burden when transitioning between production lots.
• Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.

If your protocol requires direct on-membrane analysis by microscopy or culture, the surface characteristics and dimensional tolerances described above give you a substrate that performs consistently from disc to disc. For exactly this reason, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
