Agilent, 01078-60003, Analytical head assembly, used with 1260 Infinity liquid chromatography systems

The Agilent analytical head assembly is a replacement pump-head component used in selected 1260 Infinity liquid chromatography solvent-delivery systems. The pump head forms part of the high-pressure flow path responsible for moving mobile phase toward the injector and analytical column. An appropriately maintained pump head supports consistent liquid delivery and helps preserve stable chromatographic retention and detector response. This complete head assembly is intended for repair or replacement when diagnosis identifies a pump-head problem, such as wear or damage within the mechanical fluid-delivery section. It should not be confused with an inlet-valve cartridge, a pump head adapter, or a complete LC pump module. Correct fit depends on the specific 1260 Infinity pump configuration.
