Syringe Filters, 25 mm, PTFE, 0.45 um porosity. Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58045EP25K Antarisz™ Syringe Filters are economical, high-throughput membrane filters designed for HPLC sample preparation and filtration of aggressive solvents. Featuring a 0.45 µm hydrophobic PTFE membrane, these filters deliver exceptional chemical resistance and fast flow rates, making them ideal for sample clarification and prefiltration of organic and chemically challenging solutions.
PTFE membranes are naturally hydrophobic, making them the preferred choice for organic solvents, strong acids, and aggressive chemical environments where other membrane materials may degrade. For aqueous applications, the membrane can be pre-wetted with alcohol to initiate flow.
The 0.45 µm pore size is optimized for clarification and prefiltration, offering higher flow rates and reduced clogging compared to finer membranes.
The 25 mm diameter supports higher sample volumes and improved throughput, making these filters ideal for routine and high-volume laboratory operations. The polypropylene housing ensures durability, chemical compatibility, and reliable performance.
Packaged in a 1000/case bulk format, these filters are ideal for high-volume laboratories and provide a cost-effective alternative to premium pharma-grade filters and leading brands.
