The Summit® P680A HPLC pump is a reliable workhorse for isocratic separations and, as a makeup pump, for LC-MS applications with postcolumn flow splitting. You can operate the P680 isocratic pump stand-alone or using the Chromeleon® Chromatography Management System. | | Achieve Low Detection Limits
Achieve lowest detection limits without the need for a pulse damper. SmartFlow TM pump technology eliminates pulsation at its source. Without any baseline disturbance from pulsation, you can detect trace analytes at the maximum sensitivity of your detector. | Precise Retention Times
Achieve precise retention times with strong DC motors and high-precision piston drives. | Reliability and Continuous Optimal Operation
The P680A has a rugged design, with an active rear-seal wash system as standard, and with advanced System Wellness technology, including piston-seal tightness monitoring. | Application Flexibility
With a flow rate range from 1 µL/min to 10 mL/min, and system pressures up to 50 MPa (7250 PSI) you can run microbore to small scale semipreparative applications with the same pump. | Easy to Use and Maintain
Direct front-panel access and a flip-up front cover make the pump easy to use and easy to maintain. |
