Source Microplate Survey - Labcyte Echo 520 User Manual

Source microplate survey

Prior to each run, the Echo liquid handler scans the fluid in each source
microplate well.
During the microplate survey, the acoustic transducer is moved beneath
each well. A pulse of acoustic energy is transmitted up through the bottom
of the microplate into the fluid in the well.
The low energy acoustic pulses used during the source plate survey does
not eject droplets of fluid, it measures the fluid composition, impedance,
and calculates the well fill height for each individual source well.
If the fluid is very stable, the user can go to the Transfer Option in the
Advanced tab to schedule surveys to be performed less often (after a
designated number of runs) for quicker transfer throughput.
A source microplate survey can also detect empty wells, out-of-range fluid
fill volumes, or an incorrectly positioned acoustic transducer (under a well
wall).
