HOW IT WORKS
Fill Mode
The resilient dispense tube is
pinched by the bottom piston,
closing the material path to
the dispense needle.
Dispense Ready
The top piston moves forward to
stop the material supply from the
reservoir and the bottom piston
releases the dispense tube.
Dispense Mode
The top dispense piston moves
forward until stopped by the
micrometer stroke adjustment,
squeezing a precise amount of
material out of the dispense tube.
