Eluent
Selection |
Four different eluent components; each can be proportioned from 0 to 100% |
| Pump | Dual-piston, variable speed, 100 µL (standard bore), 25 µL (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 µL
Microbore pump head: <300 µL |
This refurbished DIONEX GP50 Gradient Pump is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included. Multiple available.
