Syringe Filters, 25 mm, Cellulose Acetate, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045EC25K 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 provide fast flow rates with very low protein binding, making them ideal for sample clarification and prefiltration.
Cellulose acetate membranes are naturally hydrophilic, allowing direct use with aqueous solutions without pre-wetting. Their low protein binding properties ensure maximum recovery of proteins, enzymes, and biomolecules, making them highly suitable for biological and analytical applications.
The 0.45 µm pore size is optimized for clarification and prefiltration, offering higher flow rates and reduced clogging compared to finer membranes. This makes these filters ideal for preparing samples prior to final filtration or direct HPLC analysis.
The 25 mm diameter supports higher sample volumes and faster throughput, improving efficiency in routine and high-volume workflows. The polypropylene housing ensures broad chemical compatibility and durability.
Packaged in a 1000/case bulk configuration, these filters are ideal for high-volume laboratories and serve as a cost-effective alternative to premium pharma-grade filters and leading brands.
