Agilent, 5191-5911, SF, nylon, 25 mm, 0.45 µm

Agilent 25 mm nylon syringe filters with a 0.45 µm pore rating remove suspended particles from suitable liquid samples immediately before analysis. Each unit combines a nylon membrane and a syringe-compatible housing, enabling pressure-driven filtration without a separate holder or vacuum filtration assembly. The 25 mm format provides a practical filtering area for routine analytical sample preparation. The 0.45 µm pore rating is suited to particulate clarification where the method does not require the finer 0.2 µm filtration cutoff. Filtered samples can help reduce deposits in chromatographic injection hardware and columns, but filtration does not remove dissolved contaminants or guarantee a sterile sample. Verify solvent compatibility with nylon and assess recovery of any analyte that could bind to the membrane. Consistent filtration technique, including control of applied pressure and initial filtrate handling, improves comparability between samples. The 1,000-filter pack is intended for laboratories handling repeated sample-preparation runs.
