This Dionex GS50 Gradient Pump is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included.
| Specification | |
| Eluent Selection | Four different eluent components; each eluent can be proportioned from 0% to 100% |
| Pump | Dual-piston (in series), variable speed, 100 µL per revolution |
| Settable Flow Range | 0.0 mL/min, or from 0.05 to 5.0 mL/min in increments of 0.01 mL/min. Note: The GS50 is optimized for operation at 1.5 mL/min or less |
| Proportioning Type | Low pressure |
| Compositional Range | 0% to 100% in 0.1% increments |
| Gradient Linearity | Four concave, four convex, one linear |
| Flow Accuracy | <1% of set value or ± 2 µL/min, whichever is greater |
| Flow Precision | <0.2% |
| Compositional Accuracy | <± 1% |
| Operating Pressure | 35 MPa (5000 psi), maximum |
|
High Pressure Limit |
691 kPa to 35 MPa (100 to 5000 psi) in increments of 0.1 MPa (14 psi); trips instantaneously |
| Low Pressure Limit | 0 to 34 MPa (0 to 4900 psi) in increments of 0.1 MPa (14 psi); a start-up delay prevents false tripping |
| Delay Volume |
Low delay volume: <400 µL Standard delay volume: <800 µL |
| Pressure Ripple | <1% at 13.8 MPa (2000 psi) and 1.0 mL/min |
