Thermo Scientific™ UltiMate® 3000 Dual-Gradient Nano/Cap/Micro Pump by Thermo Fisher Scientific

It provides two independent ternary low-pressure gradients; the UltiFlow™ eluent delivery system allows flow rates down to 50 nL/min.

• Wide flow rate range from 50 nL/min to 2.5 mL/min (depending on split ratio)
• Dual-gradient pump with two independent ternary gradient pumps
• Easily convertable between nano, capillary, and micro flow rates
• UltiFlow technology for constant flow, independent of eluent composition and backpressure
• Active rear-seal wash system for increased pump uptime
• Superior gradient accuracy and precision
• Biocompatible option

The Dual-Gradient Nano/Cap/Micro Pump is used primarily for bioanalytical studies such as MS-based proteomics. It enables preconcentration, on-line and off-line multidimensional LC applications, and complex proteomic workflows, such as protein prefractionation, protein/peptide separation, and peptide mapping. It is an essential part of the Proteomics MDLC system.
