Catalog Number - CS10-58022ER25C

The CS10-58022ER25C Antarisz™ Syringe Filters are economical, high-performance membrane filters designed for HPLC sample preparation, biological analysis, and mixed solvent filtration. Featuring a 0.22 µm regenerated cellulose (RC) membrane, these filters provide excellent compatibility with both aqueous and organic solvents, making them highly versatile for a wide range of laboratory applications.

Regenerated cellulose membranes are naturally hydrophilic, allowing direct use with aqueous solutions without pre-wetting. Their very low non-specific binding ensures maximum recovery of proteins, peptides, and sensitive analytes, making them ideal for biological and pharmaceutical testing.

Manufactured without binders, surfactants, or wetting agents, RC filters offer low extractables, providing clean baselines essential for HPLC, dissolution testing, and other analytical techniques.

The 25 mm diameter enables higher sample throughput and faster filtration compared to smaller formats, while maintaining low hold-up volume (<100 µL) for improved sample recovery. The polypropylene housing ensures broad chemical compatibility and durability.

Antarisz™ syringe filters are positioned as a cost-effective alternative to premium pharma-grade filters and leading brands, delivering consistent, reliable performance for routine laboratory workflows.
