Isocratic Pump
The figure shows the installation plan for capillary and tubing on
the isocratic version of the pump. If you own a different version
of the pump, see the corresponding chapter for installation
instructions.
The gray lines represent the connection of the solvents to the
pump and the black lines represent the connection of the piston
backflushing.
Piston backflushing The flushing solution is re-used. Since the flow path is circular,
