Syringe Filters, 25mm, Polypropylene, 0.22um Pore Size. Turquoise Polypropylene, AQ Brand. 50/PK.
Additional Info:
The 58022-PP25-A AQ™ Syringe Filters are pharmaceutical-grade polypropylene membrane filters designed for HPLC sample preparation, sterile filtration, and dissolution testing in regulated laboratory environments. Featuring a 0.22 µm polypropylene (PP) membrane, these filters provide broad chemical compatibility, low extractables, and reliable analytical performance.
Polypropylene membranes are naturally hydrophilic with minimal conditioning required, making them suitable for aqueous and organic solvents, including acids and bases. This makes them an excellent choice for general-purpose sterile filtration across diverse applications.
✅ Critical Compliance Advantage (No Flush Required)
Validated to meet key regulatory standards:
US FDA CFR Title 21, Part 210.3(b)(6) – minimum fiber release
USP <788> – particulate matter in injectables
USP “Sterile Water for Injection”
Benefits:
✅ No initial flushing required
✅ No 200 µL discard required
✅ Extractable-free from first filtrate
✅ Reduces risk of failed methods
Performance & Design
The 0.22 µm pore size is optimized for sterile filtration and fine particulate removal, ensuring maximum protection of analytical systems.
The polypropylene membrane offers excellent chemical resistance, enabling reliable use with aqueous solutions, organic solvents, acids, and bases.
The 25 mm format supports larger sample volumes, making it ideal for routine and high-throughput sterile workflows.
The 16-channel outlet design reduces back pressure, allowing smooth filtration with less hand force.
The turquoise housing allows easy identification of 0.22 µm PP filters, and each pack includes a Certificate of Analysis.
