Thermo Scientific Dionex GP50-2 Gradient Pump HPLC / FPLC Pump

Product Information

The Dionex GP50-2 Gradient Pump is an integral part of a Dionex chromatography system. It is a microprocessor-based, dual-piston, variable-speed, gradient delivery system designed to blend and pump mixtures of up to four different eluents at precisely controlled flow rates. The pump can deliver the selected eluent composition isocratically, or as a multistep linear or curved gradient. Known for precision and control, this Thermo Scientific Gradient Pump is a workhorse in the lab and is essential for a wide range of applications in liquid chromatography, pharmaceutical research, and environmental analysis. The current condition indicates that some repairs are needed, however, its functionality is not compromised. Unique features include user-selectable constant pressure or constant flow feedback control, low pressure and high pressure limits, isocratic and gradient pump modes, pressure resolution, and more. With its agile performance and dependable gradient delivery, the Thermo Scientific Dionex GP50-2 is a staple in laboratories striving for reliability and precision.

• Microprocessor-based dual-piston gradient pump
