Recommended Use

The HPG-3400RS Pump is with its industry-leading performance and reliability the best choice for any ultrahigh-speed and ultrahigh-resolution application. With an unrivaled flow-pressure footprint, the RSLC pump is the most flexible binary UHPLC pump on the market.

Simple Method Transfer

UltiMate 3000 Standard (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.
