Syringe Filters, 13mm, Nylon, 0.22um Pore Size. Purple Polypropylene, AQ Brand. 50/PK.
Additional Info:
The 58022-N13-A AQ™ Syringe Filters are pharmaceutical-grade, high-performance membrane filters engineered for HPLC sample preparation, sterile filtration, and dissolution testing in regulated laboratory environments. Featuring a 0.22 µm Nylon‑66 membrane, these filters deliver exceptional consistency, ultra-low adsorption, and extractable-free performance, ensuring maximum sample purity and reproducible analytical results.
The 13 mm format is optimized for low sample volume applications, providing efficient filtration with minimal sample loss, making it ideal for analytical labs and method development workflows handling limited or high-value samples.
✅ Critical Compliance Advantage (No Flush Required)
These filters are validated and certified to meet stringent regulatory requirements, including:
US FDA CFR Title 21, Part 210.3(b)(6) for minimum fiber release
USP <788> for particulate matter in injectables
USP requirements for “Sterile Water for Injection”
Because of this validated performance:
✅ No initial flushing is required
✅ No need to discard the first 200 µL of filtrate
✅ Preserves valuable samples—critical in low-volume workflows
✅ Saves time and reduces risk of failed methods and investigations
👉 This delivers a significant operational and compliance advantage for QC/QA laboratories, where sample conservation, reproducibility, and audit readiness are essential.
Performance & Design
The 0.22 µm pore size is optimized for sterile filtration and fine particulate removal, ensuring maximum sample clarity and protection of analytical systems.
Nylon‑66 membrane chemistry provides broad compatibility with aqueous and organic HPLC solvents, while maintaining ultra-low adsorption—even for charged analytes, supporting accurate quantitation.
The 13 mm design minimizes hold-up volume, maximizing recovery from small or valuable samples, making it ideal for precision analytical workflows.
The purple color coding allows quick identification of 0.22 µm nylon filters, and each pack includes a Certificate of Analysis for full traceability and compliance.
