Supor Membrane, 0.45um, 47mm, White, Gridded, Gamma Irradiated, Bulk w/ Parchment Separators, 200/Pk SKU: 60043

Supor (PES) Membrane Filters - 60043

Designed to deliver reproducibility and confidence across critical sample types, the Pall 60043 provides the filtration consistency that method validation demands. Asymmetric polyethersulfone construction places the tightest pore layer at the upstream membrane surface, maximizing retention efficiency while the open substructure sustains flow. Consequently, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• 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.
• Stable performance at operating temperatures reaching 55°C ensures the membrane handles heated applications without pore distortion or structural compromise.
• Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.

Whether your method calls for gravimetric analysis, particle visualization, or microbial enumeration, the pore consistency documented above ensures your results reflect the sample, not the filter. With these demands 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
