Changing the Picking Head
Remove Head:
Click the Remove Head icon under Utility processes. This will move the head into the
appropriate position.
Remove all of the picking tubing from the left-hand side of the head. A microplate lid may
be placed under the picking head to collect any drops of water.
Undo the thumbscrew on the right-hand side, which secures the head to the actuator
assembly, taking care not to lose the washer.
Slide the head out of the actuator, being careful not to damage the pins.
Replace Head:
Click the Replace Head icon under Utility processes. This will move the head into the
appropriate position.
Slide the head into the actuator.
Tighten the thumbscrew on the right-hand side to secure the head.
Fit the picking tubing to the tube connectors starting at the back and working forward,
making sure that each tube is fitted to the correct connector.
Follow the instructions to purge and align the pins.
Important note: When handling the picking head take care that the pins are not
knocked. Damage to pins may produce unreliable results and can cause serious
damage to ClonePix 2. If any pins are suspected to have incurred damage please
replace them immediately.
Changing or Replacing Picking Pins
Occasionally the pins may need to be removed from the picking head for cleaning or to
change to a different pin type.
Remove the pins from the head by unscrewing each one anti clockwise with the Pin Removal
Key (X4948).
Prior to re-fitting, ensure that each pin has an O-ring (X1036) on the thread. Screw the pins
back into the head clockwise using the Pin Removal Key just until resistance is felt. Avoid
over-tightening.
