Syringe Filters, 13 mm, RC, 0.45 um porosity. Polypropylene, Antarisz Brand. 100/PK.
Additional Info:
The CS10-58045ER13C Antarisz™ Syringe Filters are economical, high-performance membrane filters designed for HPLC sample preparation, biological filtration, and mixed solvent applications. Featuring a 0.45 µm regenerated cellulose (RC) membrane, these filters deliver fast flow rates with ultra-low non-specific binding, making them ideal for sample clarification and prefiltration with maximum analyte recovery.
Regenerated cellulose membranes are naturally hydrophilic, allowing immediate use with aqueous samples without pre-wetting. Their very low binding characteristics make them particularly suitable for proteins, peptides, and other sensitive biomolecules.
The 0.45 µm pore size is optimized for sample clarification and prefiltration, offering higher flow and reduced clogging compared to finer membranes.
RC membranes are manufactured without binders, surfactants, or wetting agents, providing low extractables and clean baselines, which is critical for HPLC, dissolution testing, and analytical workflows.
The 13 mm format is ideal for low sample volumes, delivering efficient filtration with low hold-up volume (<30 µL). The polypropylene housing ensures broad chemical compatibility and durability.
Antarisz™ syringe filters offer a cost-effective alternative to premium pharma-grade filters and leading brands, delivering consistent, reliable performance.
