Catalog Number - CS10-58045EV25K

The CS10-58045EV25K Antarisz™ Syringe Filters are economical, high-throughput 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 deliver 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, allowing efficient filtration of aqueous samples while maintaining compatibility 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, 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 these filters ideal for larger volumes and high-throughput environments. With a low hold-up volume (<120 µL), they help maximize recovery and minimize waste.

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

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