Enjoy the flexibility of a quaternary pump with the fast gradient performance of a binary pump. The Thermo Scientific Dionex™ UltiMate Rapid Separations LPG-3400XRS Extended Pressure Range Quaternary Pump is an LC/MS optimized quaternary UHPLC pump offering state-of-the-art performance for high speed and ultrahigh resolution applications. The compact pump head design, with a gradient delay volume of just 200µL, supports ballistic gradients for ultrahigh throughput. A combination of speed and flexibility in solvent proportioning makes this pump the first choice as an LC front-end for MS and MS/MS.
Features
