Supor 450Membrane Disc Filters, 0.45um - 50mm, Plain, 100/Pk SKU: 60174

Supor (PES) Membrane Filters - 60174

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Complementing this, ultra-low protein binding surface chemistry minimizes adsorptive losses during filtration of dilute protein solutions, growth factor preparations, and cell culture supplements. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.
• Consistent lot-to-lot performance supports standardized filtration protocols, reducing the revalidation burden when transitioning between production lots.
• Rigorous quality controls validate retention performance at rated pore sizes, positioning Supor as a primary membrane choice for critical filtration in biopharmaceutical production.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 55°C, supporting heated filtration protocols.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
