The 515 HPLC pump is a programmable, free-standing HPLC pump available in isocratic, gradient, and semi-preparative configurations:
- Precise stepper motor control (48 steps/µL resolution) of dual reciprocating pistons
- Non-circular drive gears provide smooth, uniform eluent delivery
- User-programmable flow rate calibration and compressibility compensation factors ensure straightforward pump operation qualification
- Tests to retention time variations of less than 0.1% for highly reproducible peak performance
- Easy-to-read display and keypad for error-free programming
- Automatic purging and flow calibration
| Item | Specification |
| Operating temperature | 4 to 40 °C |
| Humidity | 20 to 80%, noncondensing |
| Audible noise | <70 dB(A) at operator position |
| Solvent compatibility | Solvents consistent with materials of construction. Salts and buffers can reduce seal life, especially at pressures in excess of 3000 psi. |
| Programmable flow rate range:100-µL heads and 225-µL heads |
0.000 to 10.000 mL/min, in 0.001-mL/min increments0.000 to 22.5 mL/min, in 0.001-mL/min increments |
| Maximum operating pressure | Maximum operating pressure |
| Pressure ripple (one pump) | ≤2.0% at 1 mL/min, degassed methanol, at 1000 psi Backpressure |
| Flow precision | ±0.1% RSD of retention time at 1 mL/min, 1000 to 2000 psi, paraben PQ test, or 2 seconds SD |
| Flow accuracy | ±1.0% of setting at 1 mL/min, or 30 µL/min, whichever is larger, using degassed methanol at 1000 to 2000 psi backpressure |
This refurbished Waters 515 HPLC Pump is in great condition. It has been tested at SpectraLab Scientific.
A 90 day warranty is included. Multiple available.
