Syringe Filters, 25 mm, RC, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045ER25K Antarisz™ Syringe Filters are economical, high-throughput 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 direct filtration of aqueous samples without pre-wetting. Their very low binding characteristics ensure excellent recovery of proteins, peptides, and sensitive biomolecules, making them highly suitable for biological and pharmaceutical workflows.
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 methods.
The 25 mm diameter is designed for higher sample throughput and faster filtration, making these filters ideal for larger volume samples and high-throughput laboratory environments. With a low hold-up volume (<100 µL), they help maximize sample recovery while minimizing waste.
Packaged in a 1000/case bulk format, these filters are ideal for high-volume laboratories and provide a cost-effective alternative to premium pharma-grade filters and leading brands.
