Catalog Number - CS10-58022ER13K

The CS10-58022ER13K 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 chemical compatibility with both aqueous and organic solvents, making them highly versatile for demanding analytical workflows.

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

These filters are manufactured without binders, surfactants, or wetting agents, resulting in low extractables and clean analytical baselines, which is critical for reproducible HPLC and dissolution testing results.

The 13 mm format is optimized for low-volume samples, providing efficient filtration with low hold-up volume (<30 µL). The polypropylene housing delivers broad chemical compatibility and durability.

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