Catalog Number - CS10-58045EN25K

The CS10-58045EN25K Antarisz™ Syringe Filters are economical, high-throughput membrane filters designed for HPLC sample preparation and general laboratory filtration. Featuring a 0.45 µm nylon membrane, these filters deliver fast flow rates and broad chemical compatibility, making them ideal for sample clarification and prefiltration of both aqueous and organic solutions.

Nylon membranes are naturally hydrophilic yet solvent-resistant, allowing efficient filtration of aqueous samples, alcohols, and many organic solvents commonly used in HPLC mobile phases. This versatility makes them well suited for mixed solvent systems and routine analytical workflows.

The 0.45 µm pore size is optimized for clarification and prefiltration, providing higher flow rates and reduced clogging compared to finer membranes.

The 25 mm diameter is designed for higher sample throughput and faster filtration, making it ideal for larger sample volumes and high-volume lab environments. Combined with a low hold-up volume (<120 µL), these filters help maximize sample recovery while minimizing waste.

Constructed with a double-sealed polypropylene housing, these filters offer durability and leak-resistant performance, while the female luer lock inlet and male luer slip outlet ensure secure syringe compatibility.

Packaged in a 1000/case bulk format, these filters are ideal for high-volume laboratories and provide a cost-effective alternative to premium pharma-grade filters and leading brands.
