Supor Membrane Disc Filter - 0.45um, 47mm, Gridded, 100/Pk SKU: 61854

Supor (PES) Membrane Filters - 61854

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. On the performance side, full pH compatibility from 1 to 14 allows Supor membranes to handle acidic mobile phases, neutral buffers, and alkaline cleaning solutions without performance degradation. Because of this, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• 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.
• 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.

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. In these cases, 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
