Agilent Certified Pre-Owned 1290 Binary Pump

With the Agilent Certified Pre-Owned refurbishment process, you can be confident that the Certified Pre-Owned 1290 Binary Pump will provide you the same performance as a new module.

The 1290 Binary Pump comprises two identical pumps integrated into one housing. Binary gradients are created by high-pressure mixing. A degassing unit is included for applications that require best flow stability, especially at low flow rates, for maximum detector sensitivity. The flow path of the pump has been optimized for minimal delay of gradients.  

The 1290 Binary Pump is capable of delivering flow in the range of 0.05-5 mL/min against up to 1200 bar. Typical applications are high throughput methods with fast gradients on high resolution 2.1 mm columns. A solvent selection valve allows forming binary mixtures (isocratic or gradient) from one of two solvents per channel. Active seal wash is included for use with concentrated buffer solutions.
