WebHPLC solvent filters & solvent filtration assembly are used to filter mobile phase buffers as a daily routine part of HPLC sample analysis. The Agilent InfinityLab solvent filtration assembly is manufactured from high-quality borosilicate glass components and can hold a 47 mm HPLC filter membrane to remove particulates from liquid media. WebUse only clean, HPLC-grade solvents. A dirty solvent can cause baseline noise and drift and clog solvent filters with particulate matter. HPLC-grade solvents generally maintain their purity from lot to lot; use them to ensure the best possible results. After adding solvent modifiers (buffers) and adjusting pH, filter the solvents using a
