Catalog Number - CS10-58045EC13C

The CS10-58045EC13C 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 cellulose acetate (CA) membrane, these filters provide fast flow rates with low protein binding, making them ideal for aqueous samples and high-recovery applications.

Cellulose acetate membranes are naturally hydrophilic, allowing immediate use without pre-wetting. Their very low protein binding helps ensure maximum recovery of proteins, enzymes, and biomolecules, which is critical in biological and analytical workflows.

The 0.45 µm pore size is ideal for general clarification and prefiltration, offering higher flow and reduced clogging compared to finer (0.22 µm) membranes.

The 13 mm format is optimized for low sample volumes, delivering efficient filtration with low hold-up volume, while the polypropylene housing ensures broad chemical compatibility and durability.

Antarisz™ syringe filters are a cost-effective alternative to premium pharma-grade filters and leading brands, providing reliable performance for routine laboratory operations.
