Syringe Filters, 25 mm, MCE, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045EM25K Antarisz™ Syringe Filters are economical, high-throughput membrane filters designed for HPLC sample preparation, microbiological testing, and general laboratory filtration. Featuring a 0.45 µm mixed cellulose ester (MCE) membrane, these filters provide fast flow rates with reliable particulate and microorganism retention, making them ideal for sample clarification and prefiltration.
MCE membranes (cellulose acetate + cellulose nitrate) are naturally hydrophilic, allowing immediate use with aqueous solutions without pre-wetting. Their uniform pore structure ensures consistent, reproducible filtration results, especially in analytical and microbiological workflows.
The 0.45 µm pore size is optimized for clarification, particulate removal, and microbial collection, delivering higher flow rates and reduced clogging compared to finer membranes.
The 25 mm diameter supports higher sample volumes and faster throughput, improving efficiency in both routine and high-volume laboratory settings. The polypropylene housing provides broad chemical compatibility and durability.
Packaged in a 1000/case bulk format, these filters are ideal for high-volume laboratories and serve as a cost-effective alternative to premium pharma-grade filters and leading brands.
