Syringe Filters, 25 mm, RC, 0.45 um porosity. Polypropylene, Antarisz Brand. 100/PK.
Additional Info:
The CS10-58045ER25C 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 especially suitable for proteins, peptides, and other sensitive biomolecules.
The 0.45 µm pore size is optimized for clarification and prefiltration, providing higher flow rates and reduced clogging compared to finer membranes.
RC membranes are manufactured without binders, surfactants, or wetting agents, resulting in low extractables and clean baselines, which is critical for HPLC, dissolution testing, and analytical workflows.
The 25 mm diameter supports higher sample volumes and faster throughput, improving efficiency in routine and high-volume laboratory environments. With a low hold-up volume (<100 µL), these filters help maximize sample recovery while minimizing waste.
The polypropylene housing ensures broad chemical compatibility and durability for consistent performance.
Antarisz™ syringe filters provide a cost-effective alternative to premium pharma-grade filters and leading brands, delivering reliable results for routine laboratory use.
