Waters, WAT088084, FILTER INSERT ASSY

FILTER INSERT ASSY is used for replacement of the precolumn solvent filter insert in Waters Alliance HPLC instrument fluid paths. The stainless-steel insert provides 2 µm filtration at the filter installed between the pump and injector, helping remove particulate material from the mobile phase before it reaches downstream injection components. This is an instrument service part rather than a packed HPLC analytical column, syringe filter or sample-preparation membrane. It is compatible with the Waters 2695 Separations Module, 2695 D Dissolution Separations Module and 2795 Separations Module. The replacement assembly is supplied as one unit per package and carries an annual replacement schedule. The stainless-steel construction and location in the instrument's solvent path make it appropriate for routine HPLC maintenance when restoring filtration performance at the precolumn filter position. The replacement part supports reliable operation of the corresponding Alliance fluidic system without changing the chromatographic stationary phase, analytical column dimensions or sample preparation method. Its principal selection criteria are the 2 µm filter insert, exact location between pump and injector and compatibility with the named Waters modules.
