Series 12x6 Constant Flow Dual Head Pump, 0.001-12ml/min. 5000psi (PEEK), 6000psi (SS)

The Series 12x6 Constant Flow Pump for the most demanding Analytical Chromatography Applications

The Series 12x6 Constant Flow Pump has been designed for analytical to small-scale preparative chromatography applications. The patented low-dead-volume pulse damper and dual piston mechanism make this pump virtually pulse-free, and provide unmatched performance for the most demanding applications. The unit provides constant flow rates from 0.001 to 12.0 ml/min and is typically suitable for columns from 2mm up to 22mm ID.

The Series 1500 drive features a linear cam and pressure compensation to provide accurate gradients in the high- or low-pressure mode.

Standard controls include RS-232 serial communication port and Run/Stop inputs, remote frequency and remote voltage controls, real-time pressure monitoring, and constant flow.

The use of modern digital stepper motor technology and high-performance mechanical design provide accurate pressures to 6,000 psi.
