Supor (PES) Membrane Filters - 66552
Precision-manufactured Hydrophilic membrane with a verified 1.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Full pH compatibility from 1 to 14 allows Supor membranes to handle acidic mobile phases, neutral buffers, and alkaline cleaning solutions without performance degradation. In combination, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.
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.
- 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.
- Ultra-low protein binding preserves the biological activity of growth factors, cytokines, and other sensitive proteins during membrane passage.
- Stable performance at operating temperatures reaching 55°C ensures the membrane handles heated applications without pore distortion or structural compromise.
Microbial enumeration methods require complete retention at rated pore size and a growth-supporting surface. The membrane specifications above confirm both requirements for your culture-based workflows. 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.
