Dionex GP50 Gradient Pump HPLC/FPLC/GC/CE Laboratory Chromatography System

Product Information

The Dionex GP50 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. **WORKS AND RUNS BUT IS MISSING BOTH FRONT PLATES INCLUDING SCREEN AND CONTROL(NEEDS WORK). The Dionex GP50 Gradient Pump is designed to provide precise eluent blends and deliver them isocratically or as part of a multistep linear or curved gradient. It is an integral part of any lab's chromatography system, with versatile applications in analytical chemistry, pharmaceuticals, and environmental analysis.

• Microprocessor-based dual-piston design
• Variable-speed with gradient delivery system
• Isocratic and multistep gradient eluent delivery capability

• Eluent Selection - Four different eluent components; each can be proportioned from 0 to 100%
• Pump - Dual-piston, variable speed, 100 L (standard bore), 25 L (microbore) stroke, user-selectable constant pressure or constant flow feedback control
• Flow Rate - Standard bore pump head: 0.04 to 10.0 mL/min linearly variable in increments of 0.01 mL/min, Microbore pump head: 0.01 to 2.50 mL/min linearly variable in increments of 0.01 mL/min
• Operating Pressure - 35 MPa (5000 psi) maximum
• Pressure Resolution - 0.07 MPa (10 psi)
• High Pressure Limit - 0 to 35 MPa (0 to 5000 psi) in increments of 0.05 MPa (7.25 psi); trips instantaneously
• Low Pressure Limit - 0. to 35 MPa (0 to 5000 psi) in increments of 0.05 MPa (7.25 psi); trips after a time-out of 0.4 mL for the standard bore GP50 or 0.1 mL for the microbore GP50
• Delay Volume (No Mixer) - Standard bore pump head: <700 L, Microbore pump head: <300 L
