Dionex Ultimate 3000 LPG-3400SD Quaternary Analytical Pump

For flexibility across a broad range of analytical LC applications with the highest degree of choice in solvent proportioning and mixing, the Dionex UltiMate LPG-3400SD Standard Quaternary Pump is the pump of choice. Up to four solvents may be used for convenient method development, system flushing or solvent preparation. With support for pressures up to 62 MPa (9,000 psi/620 bar) at flow rates of up to 10mL/min., the UltiMate 3000 SD pumps excel in standard LC applications while offering full compatibility with fast UHPLC separations.

The LPG-3400SD pump is ideally-suited for method development as well as analytical research and routine analysis in the pharmaceutical, food and beverage and environmental industries. It supports short sub-2µm particle columns for faster analysis while consuming less solvent.

Simple Method Transfer

UltiMate 3000 SD and Rapid Separation (RS) pumps and system configurations provide similar gradient delay and extra column volumes. This simplifies the method transfer between method development labs commonly using UHPLC pumps and QC and production labs with their standard LC pump setups.
