Featuring a naturally hydrophilic polyethersulfone (PES) membrane with a 0.45um pore size and a 25mm membrane diameter, these syringe filters deliver fast, high-throughput clarification of aqueous and organic solutions. The PES membrane provides low protein binding and rapid flow, while a modified housing bidirectionally supports the membrane to allow either sample injection or aspiration. Each filter is ultrasonically welded and integrity tested to ensure a proper fit and eliminate potential filter by-pass.
Key PES Membrane Characteristics
- Naturally hydrophilic surface that wets out readily for efficient filtration of aqueous solutions.
- Low protein binding to preserve sample integrity and maximize analyte recovery.
- 0.45um pore size suited to sample clarification and particulate removal ahead of analysis.
- Fast flow rates that increase throughput and speed of sample preparation.
- Broad compatibility with both aqueous and organic solutions.
Key Construction Characteristics
- Transparent polypropylene housing with a 25mm membrane diameter.
- Luer-Lok inlet and Luer Slip outlet connection for secure syringe attachment and convenient dispensing.
- Ultrasonically welded and integrity tested to eliminate filter by-pass.
- Nonsterile, supplied 500 per pack.
- Each filter labeled with the specific filter material and pore size for easy identification outside its original packaging.
These filters maintain reliable, reproducible performance across routine and critical filtration workflows. The low protein binding membrane and lower hold-up volume help preserve sample integrity and maximize recovery. Clear housing and individual labeling support confident identification at the bench.
