Used DIONEX GP40 #9113324 for sale

DIONEX GP 40 is an integrated dual-piston pump designed for high performance liquid chromatography (HPLC) applications. The pump features precise flow control and low noise operation. It is capable of delivering flow rates up to 4 mL/min with a pressure range of up to 1000 bar. GP 40 features a dual-piston design, allowing for two different flow rates to be achieved while keeping the pressure of the sample and mobile phase constant. This feature makes it very useful for multi-dimensional chromatography. DIONEX GP 40 is equipped with back-pressure regulators and pressure transducers that allow accurate control of the pressure within the system, enabling precise flow rate control. The pressure profile is adjustable using a convenient knob on the front panel. The relationship between the stroke length and flow rate is extremely linear, making it easy to compare results with previous experiments. GP 40 also features a low noise operation, with pumps within a range of 2-4dB at 100 bar, resulting in a quiet and efficient lab environment. For added safety and convenience, DIONEX GP 40 comes with a safety shut-off switch, temperature-resistant connectors, and an easy to read pressure indicator. The pump also includes an onboard microprocessor, allowing for additional programmability and operation of the pump. Overall, GP 40 is a reliable and accurate pump ideal for HPLC applications. By offering superior performance, precise flow control, and low noise operation, the pump provides the highest quality results in any HPLC system.
