Supor 200 Membrane Disc Filters, 0.2um - 293mm, Tabbed, 25/Pk SKU: 60307

Supor (PES) Membrane Filters - 60307

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Low extractable levels ensure that Supor membranes contribute minimal background to filtered preparations used in sensitive cell culture and analytical applications. In sum, consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.
• Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.

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. Under these conditions, low extractable levels from the filter medium protect the analytical cleanliness of your filtrate, reducing the background interference that complicates trace-level analyses and forces unnecessary repeat measurements. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
