Destination Plate Gripper Stage
The destination plate gripper stage is the upper plate stage that extends from the Echo Liquid Handler. The plate gripper holds
the microplate that will receive the liquid being transferred.
When you load the plate onto the plate gripper, well A1 goes into the upper left corner (nearest the Echo model number).
Figure 17: Extended destination plate gripper stage
When the destination plate gripper stage is commanded to retract into the Echo Liquid Handler, the microplate is gripped and
simultaneously rotated down. It is in this inverted position that the microplate will be able to receive the fluid droplets ejected
upwards from the source plate wells.
Figure 18: Inverting the destination plate
As the destination plate gripper stage retracts into the Echo Liquid Handler, a sensor detects whether a plate is or is not present.
Normally, a transfer will not be executed if a destination plate is not detected. The human operator, or a controlling program, can
override the plate presence check, if necessary.
When the destination plate gripper stage extends out of the Echo Liquid Handler, the plate is rotated back to its upright position.
