515 HPLC Pump, Waters (CAT#: STEM-CPO-0739-ZJF)

The manufacturer of the 515 HPLC Pump, Waters is Waters.
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. Tests to retention time variations of less than 0.1% for highly reproducible peak performance.

Condition: Refurbished, Certified Pre-owned
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: 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
range: 100-µL heads and 225-µL heads:
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
