The Dionex Aquion RFIC pump is a microprocessor-based eluent delivery system. Its variable
speed, dual-piston series design ensures pulse-free pumping for the most demanding
applications.
The primary pump head pumps eluent into the secondary pump head (see
check valves, which prevent reverse flow through the pump, are on the bottom (inlet) and top
(outlet) of the primary pump head. The priming valve is on the front of the pump head.
To open the priming valve, turn the knob one-quarter to one-half turn counterclockwise.
When the priming valve is open, liquid can flow into and out of the primary pump head via
the port on the front of the valve.
Note The priming valve must be open when the pump is being primed with a syringe (see
