2. The operator loads the destination plate (can be microplate or slide
holder) that will receive the liquid into the Echo liquid handler.
Before retracting the destination plate, the Echo liquid handler inverts
the plate, with the open microplate wells or slide facing downward.
This step is required to receive droplets ejected UP from the source
microplate.
See “Will the fluid splash or fall out?” on page 1-4
.
Figure 1.1 Inverting the destination plate
During the transfer process, the source microplate remains in a fixed
position; the destination plate is positioned just above the source
microplate and moves simultaneously with the acoustic transducer.
The acoustic transducer moves beneath the wells. At each well, the
acoustic transducer emits acoustic energy that ejects a specified
volume of liquid upwards to the receiving well or slide on the
destination plate.
Figure 1.2 Diagram of transferring fluid
After liquid transfer, the Echo liquid handler moves the filled
destination plate out of the instrument and inverts the plate again so
that it can be removed.
3. The operator removes the destination plate containing the transferred
compound.
