Series 12x6 Pump (Organic)

Unmatched Performance for the most demanding HPLC applications.

The Series 12x6 HPLC 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 flow rates from 0.001 to 12.0 mL/min., and is typically suitable for columns from 2 mm to 22 mm ID.
The Series 12x6 drive features a linear cam and pressure compensation to provide accurate gradients in the high- or low-pressure mode.

Control Interface

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 high-performance mechanical design provides accurate pressures to 6000 psi.
