PES Syringe Filters – Low Protein Binding Hydrophilic Membrane
JM Science PES (Polyethersulfone) syringe filters are engineered for aqueous and biological sample preparation where low protein binding and minimal analyte loss are critical.
PES membranes provide excellent flow rates, strong mechanical stability, and low extractables, making them ideal for HPLC, ion chromatography, pharmaceutical QC, and environmental analysis.
Designed for laboratories that require reliable aqueous filtration without compromising recovery.
Typical Applications
• Aqueous HPLC sample preparation
• Protein and peptide solutions
• Buffer solutions
• Tissue culture media
