Syringe Filters, 13 mm, PES, 0.45 um porosity. Polypropylene, Antarisz Brand. 100/PK.
Additional Info:
The CS10-58045ES13C Antarisz™ Syringe Filters are economical, high-performance membrane filters designed for HPLC sample preparation, biological filtration, and general laboratory use. Featuring a 0.45 µm polyethersulfone (PES) membrane, these filters provide fast flow rates and 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. Known for their low protein binding and high flow performance, PES filters are widely used in life science, pharmaceutical, and analytical workflows 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 13 mm format is designed for low sample volumes, offering efficient filtration with minimal waste. The polypropylene housing ensures durability and broad chemical compatibility 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 applications.
