Thumbnail Filmstrip of Polyethersulfone (PES) Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Sterile, 50/Pk Images
Featuring a naturally hydrophilic polyethersulfone (PES) membrane rated at 0.22um, these sterile syringe filters deliver fast, high-throughput filtration of aqueous and organic solutions across a 25mm membrane diameter. The membrane is supported within a 33mm modified acrylic housing that bidirectionally supports the membrane, allowing both sample injection and aspiration, and the unit terminates in Luer-Lok/Luer Slip end fittings for secure connection to standard syringes. Provided sterile and packaged 50 per box, each filter is individually labeled with its membrane material and pore size for easy identification once removed from packaging.
Key Polyethersulfone (PES) Membrane Characteristics
- Naturally hydrophilic membrane that wets readily for rapid filtration of aqueous solutions
- Low protein and drug binding for maximum recovery of critical analytes and samples
- Fast flow rates and high throughput to speed sample preparation
- Wide chemical compatibility across aqueous, organic, and alcohol solutions
- Strength and dimensional stability suited to manual or automated handling
Key Construction Characteristics
- Transparent modified acrylic housing, 33mm diameter, ultrasonically welded for integrity
- Luer-Lok inlet and Luer Slip outlet connections for compatibility with standard syringes
- Supplied sterile and integrity tested to verify proper filter fit and weld and eliminate filter by-pass
- Maximum operating pressure up to 75 psi
- Packaged 50 filters per box
These filters maintain reliable, reproducible performance for routine and critical filtration work. The low hold-up volume preserves sample recovery, while the integrity-tested weld helps protect sample integrity by preventing filter by-pass. The combination of low binding and fast flow makes them well suited for sensitive analytical and life science workflows.
