Catalog Number - CS10-58045EV25C

The CS10-58045EV25C Antarisz™ Syringe Filters are economical, high-performance membrane filters designed for HPLC sample preparation, biological filtration, and general laboratory workflows. Featuring a 0.45 µm hydrophilic PVDF (polyvinylidene fluoride) membrane, these filters provide fast flow rates, low protein binding, and broad chemical compatibility, making them ideal for sample clarification and prefiltration.

Hydrophilic PVDF membranes do not require pre-wetting, enabling efficient filtration of aqueous samples while remaining compatible with many organic solvents. Their low non-specific binding and low extractables support clean chromatographic baselines and high analyte recovery, especially in biological and analytical applications.

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

The 25 mm diameter allows for higher sample throughput and faster filtration, making these filters ideal for larger sample volumes and high-throughput laboratory workflows. With a low hold-up volume (<120 µL), they help maximize recovery while minimizing waste.

Constructed with a durable polypropylene housing, these filters provide chemical resistance and reliable performance, with standard luer connections for secure syringe compatibility.

Antarisz™ syringe filters offer a cost-effective alternative to premium pharma-grade filters and leading brands, delivering consistent, dependable results.
