Catalog Number - CS10-58022ER25K

The CS10-58022ER25K Antarisz™ Syringe Filters are economical, high-throughput 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 one of the most versatile membrane options for analytical laboratories.

Regenerated cellulose membranes are naturally hydrophilic, enabling efficient filtration of aqueous samples without pre-wetting. Their ultra-low non-specific binding properties ensure maximum recovery of proteins, peptides, and sensitive biomolecules, which is critical for biological and pharmaceutical applications.

These filters are produced without binders, surfactants, or wetting agents, resulting in low extractables and clean baselines, making them ideal for HPLC, dissolution testing, and other sensitive analytical methods.

The 25 mm diameter is designed for higher sample volumes and faster throughput, improving efficiency in high-volume workflows. Combined with a low hold-up volume (<100 µL), these filters help maximize sample recovery and reduce waste.

Packaged in a 1000/case bulk format, they are well suited for high-throughput laboratories and provide a cost-effective alternative to premium pharma-grade filters and leading brands.
