Agilent, 5191-5910, SF, nylon, 25 mm, 0.2 µm

Agilent 25 mm nylon syringe filters with a 0.2 µm pore rating provide point-of-use particulate filtration for suitable liquid samples before chromatographic or other analytical workflows. The integrated filter housing allows liquid to be pushed through the membrane directly from a compatible syringe, avoiding a separate vacuum-filter apparatus. The 25 mm membrane format is useful when handling sample volumes that justify a larger filtration area than very small syringe filters. A 0.2 µm rating targets finer particles than a 0.45 µm membrane, helping limit particulate transfer to sample vials, injection valves, capillaries and analytical columns. Check nylon chemical compatibility with the actual solvent mixture, because some aggressive solvents and reagents may damage the membrane or affect extractables. Prime or discard initial filtrate when required by the validated sample-preparation method. Supplied as 1,000 filters, this configuration suits high-throughput preparation where consistent filter specifications and sample traceability are important.
