Syringe Filters, 25 mm, PTFE, Hydrophobic, 0.22 um Pore Size. Translucent Polypropylene, Antarisz Brand. 1000/CS.
Additional Info:
The CS10-58022EP25K Antarisz™ Syringe Filters are economical, high-throughput membrane filters designed for HPLC sample preparation and filtration of aggressive solvents. Featuring a 0.22 µm hydrophobic PTFE membrane, these filters provide excellent chemical resistance and reliable fine particulate removal in demanding analytical workflows.
PTFE membranes are inherently hydrophobic, making them ideal for organic solvent filtration, strong acids, and chemically aggressive samples where other membranes may not perform reliably. For aqueous solutions, the membrane can be pre-wetted with alcohol to enable proper flow.
The 25 mm diameter enables higher sample throughput and faster filtration, making these filters well suited for both routine and high-volume laboratory operations.
The translucent polypropylene housing provides broad chemical compatibility and visual confirmation of filtration, while ensuring durable, leak-resistant 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.
