The Thermo Scientific Dionex UltiMate^™ 3000 Quaternary Nano/Cap/Micro Pump is equipped with the Quaternary Micro Pump LPG-3400M(B) and a Nano/Cap/Micro Flow Manager FLM-3x00(B). It supports the accurate and precise delivery of quaternary gradients with a flow rate range from 50 nL/min to 160 µL/min with the UltiFlow^™ eluent delivery system.

• Serial dual-piston operating principle, low-pressure gradient proportioning; active flow splitting and flow control
• Wide operating flow rate range from 50 nL/min to 160 µL/min. The pump can also be configured to deliver a standard LC flow rate of up to 2500 µL/min
• UltiFlow technology for constant flow independent of eluent composition and backpressure
• Superior gradient accuracy and precision
• Supports use of up to four solvents for gradient applications
• Active rear-seal wash for maximum seal lifetime
• Biocompatible option

The UltiMate 3000 Quaternary Nano Pump is used primarily as a front-end separation system for mass spectrometry in proteomic and bioanalytical analyses. The Cap/Micro pump variant is recommended for research and routine analyses of small sample amounts in drug discovery applications, particularly for drug metabolism and pharmacokinetic studies.
