Filters, Membrane, 47mm, 0.22um, Nylon. Round, AQ Brand. 100/PK.
Additional Info:
The 58522-N47 AQ Brand Membrane Filters are 47 mm nylon‑66 membrane discs designed for mobile phase filtration and laboratory applications requiring finer particulate retention.
These hydrophilic membranes provide absolute retention at 0.22 µm, making them ideal for removing very fine particles and supporting sterile filtration workflows. With minimal extractables and high purity construction, they help ensure low background noise and consistent analytical performance in HPLC and related techniques.
