Syringe Filters, 13 mm, PES, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045ES13K Antarisz™ Syringe Filters are economical, high-throughput 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 immediate 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 important.
The 0.45 µm pore size is optimized for clarification and prefiltration, offering higher flow rates and reduced clogging compared to finer membranes.
The 13 mm format is ideal for low sample volumes, delivering efficient filtration with minimal waste. The polypropylene housing ensures durability and broad chemical compatibility.
Packaged in a 1000/case bulk configuration, these filters are ideal for high-volume laboratories and provide a cost-effective alternative to premium pharma-grade filters and leading brands.
