Function
Draws in/expels solvent as part of serial flow
design.
Draws in/expels solvent as part of serial flow
design.
Allows solvent purging, priming, and venting.
Provides solvent to wash the seals of the
primary and accumulator plungers.
Maintains flow direction in the primary piston
chamber by opening in one direction only:
opens on the plunger intake stroke; closes on
the delivery stroke.
Maintains flow direction in the accumulator
piston chamber by opening in one direction
only: opens on the plunger intake stroke;
closes on the delivery stroke.
Senses backpressure developed by resistance
to solvent flow in the primary piston chamber.
Senses backpressure developed by resistance
to solvent flow in the HPLC system.
