Dionex GP50-2 Gradient Pump

The Dionex GP50-2 Gradient Pump is an integral component of Dionex chromatography systems, engineered to deliver accurate and reproducible gradients. It features a dual-piston design with variable-speed control, allowing for the blending and pumping of up to four eluents at precisely controlled flow rates. The pump can operate isocratically or perform multistep linear or curved gradients, providing flexibility for various analytical methods. A Digital Signal Processor (DSP) ensures high-speed control of pump flow and pressure, enhancing performance and reliability.
