Syringe Filters, 13mm, RC, 0.22um Pore Size. Grey Polypropylene, AQ Brand. 100/PK.
Additional Info:
The 58022-R13-C AQ™ Syringe Filters are pharmaceutical-grade regenerated cellulose (RC) membrane filters designed for HPLC sample preparation, sterile filtration, and dissolution testing in regulated laboratory environments. Featuring a 0.22 µm regenerated cellulose membrane, these filters deliver low extractables, high analyte recovery, and consistent chromatographic performance.
Regenerated cellulose membranes offer very low protein binding and minimal hold-up volume, making them ideal for protein solutions, buffers, and cell culture media, especially when maximum recovery is required.
✅ Critical Compliance Advantage (No Flush Required)
Validated to meet key regulatory standards:
US FDA CFR Title 21, Part 211.92 – minimum fiber release
USP <788> – particulate matter in injectables
USP “Sterile Water for Injection”
Benefits:
✅ No initial flushing required
✅ No 200 µL discard required
✅ Improves sample recovery and efficiency
✅ 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 RC membrane provides low adsorption and excellent recovery, making it ideal for biological and aqueous samples.
The 13 mm format is designed for low to moderate sample volumes, minimizing sample waste while maintaining efficient filtration.
Not recommended for use with strong acids or bases.
The grey housing allows quick identification of 0.22 µm RC filters, and each pack includes a Certificate of Analysis.
