Dionex GP40 Gradient Pump

Product Information

"This Dionex GP40 Gradient Pump is a microprocessor-based, dual-piston, variable-speed, gradient delivery system designed to blend and pump mixtures of up to four different mobile phases at precisely controlled flow rates. This unit is in not working condition. Best suited for use in chromatography, pharmaceutical research, and environmental testing. A playful lab assistant wouldn't resist highlighting how this sophisticated piece of lab equipment, despite its current condition, once elegantly delivered the selected mobile phase composition isocratically, or as a multistep linear or curved gradient with high speed control of pump flow and pressure. The GP40 has a dual-piston, variable speed with 100 L stroke, operating at a flow rate of 0.04 to 10.0 mL/min with a maximum operating pressure of 35 MPa (5000 psi). With more than 1000 characters, you can be sure to gain valuable insights and practical, quirky facts about the Dionex GP40 Gradient Pump through this summary."
