Syringe Filters, 25 mm, PES, 0.45 um porosity. Polypropylene, Antarisz Brand. 100/PK.
Additional Info:
The CS10-58045ES25C Antarisz™ Syringe Filters are economical, high-performance membrane filters designed for HPLC sample preparation, biological filtration, and general laboratory workflows. Featuring a 0.45 µm polyethersulfone (PES) membrane, these filters provide fast flow rates with low protein binding, making them ideal for sample clarification and prefiltration of aqueous and biological samples.
PES membranes are naturally hydrophilic, allowing direct use with aqueous solutions without pre-wetting. Their low protein binding and high flow performance make them well suited for life science, pharmaceutical, and analytical applications where sample recovery is critical.
The 0.45 µm pore size is optimized for clarification and prefiltration, delivering higher flow rates and reduced clogging compared to finer membranes.
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 (<120 µL), these filters maximize sample recovery while minimizing waste.
Constructed with a durable polypropylene housing, these filters ensure broad chemical compatibility and reliable performance.
Antarisz™ syringe filters provide a cost-effective alternative to premium pharma-grade filters and leading brands, delivering consistent results for routine laboratory applications.
