Filters, Membrane, 47mm, 0.22um, PTFE. Round, AQ Brand. 100/PK.
Additional Info:
The 58622-PT47 AQ Brand Membrane Filters are 47 mm PTFE (polytetrafluoroethylene) membrane discs with polypropylene support, engineered for high‑purity filtration of organic solvents and chemically aggressive solutions.
These hydrophobic membranes provide absolute retention at 0.22 µm, making them ideal for fine particulate removal and solvent clarification in non‑aqueous systems. With low extractables and strong chemical resistance, they support clean mobile phase preparation and reproducible chromatographic performance.
