Syringe Filters, 13 mm, Cellulose Acetate, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045EC13K Antarisz™ Syringe Filters are economical, high-throughput membrane filters designed for HPLC sample preparation, biological filtration, and general laboratory use. Featuring a 0.45 µm cellulose acetate (CA) membrane, these filters deliver fast flow rates with very low protein binding, making them ideal for sample clarification and high-recovery applications.
Cellulose acetate is naturally hydrophilic, allowing immediate use with aqueous solutions without pre-wetting. Its low protein binding characteristics ensure maximum recovery of proteins, enzymes, and biomolecules, critical for biological and analytical workflows.
The 0.45 µm pore size is optimized for sample clarification and prefiltration, providing higher flow and reduced clogging compared to 0.22 µm membranes.
The 13 mm format is ideal for small sample volumes, offering efficient filtration with low hold-up volume, while 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.
