Syringe Filters, 13mm, Nylon, 0.45um Pore Size. Green Polypropylene, AQ Brand. 100/PK.
Additional Info:
The 58045-N13-C AQ™ Syringe Filters are pharmaceutical-grade, high-performance membrane filters engineered for HPLC sample preparation and dissolution testing in regulated laboratory environments. Featuring a 0.45 µm Nylon‑66 membrane, these filters provide exceptional consistency, ultra-low adsorption, and extractable-free performance, ensuring reliable and reproducible chromatographic results.
The 13 mm format is optimized for low sample volume applications, allowing efficient filtration while minimizing sample loss—ideal for analytical labs and method development workflows where sample conservation is critical.
✅ 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 (especially critical for small volumes)
✅ Saves time and reduces risk of failed methods and investigations
👉 This creates a significant operational and compliance advantage for QC/QA laboratories, where efficiency, traceability, and method reliability are essential.
Performance & Design
The 0.45 µm pore size is ideal for sample clarification and prefiltration, offering high flow rates with reduced clogging, improving analytical efficiency.
Nylon‑66 membrane chemistry ensures broad compatibility with aqueous and organic HPLC solvents, while maintaining ultra-low adsorption—even for charged analytes, supporting accurate quantitation.
Engineered for low-volume workflows, the 13 mm design minimizes hold-up volume and sample waste, making it an excellent choice for limited or high-value samples.
The green color coding allows rapid identification of 0.45 µm nylon filters, and each pack includes a Certificate of Analysis for full compliance and traceability.
