Polyethersulfone (PES) Membrane Filters - 68124
Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Constructed for reliable operation, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. In effect, lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.
Material Specifications
- Polyethersulfone (PES) membranes deliver high flow rates with ultra-low protein binding, making them the preferred choice for biological sample filtration.
- Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
- Rigorous quality controls validate retention at rated pore sizes, positioning PES for critical pharmaceutical and biotechnology filtration.
- Engineered for rapid throughput, PES provides an asymmetric pore structure that resists premature clogging during high-volume filtration runs.
- Naturally hydrophilic, PES membranes require no pre-wetting and offer broad compatibility with aqueous buffers, alcohols, and mild organic solvents.
Air monitoring and stack emissions sampling demand a filter medium that withstands the conditions at your collection point. The material properties above define that operating envelope. Specifically, ultra-low protein binding ensures your biological filtrates retain the analyte concentrations present in the original sample, protecting yield in sensitive preparations. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
