Aspiration Issues
Table 6-6:
Aspiration Issues
Problem
Possible Causes & Remedies
The microplate is stuck on the
wash head after aspiration or
wash.
Microplates with conical or tapered bottoms
(such as certain V-bottom or small-
volume/half-area plates) might be
incompatible with aspiration and wash
operations.
Incomplete aspiration across
the entire plate.
Incorrect plate definition:
•
Verify that all plate parameters in the
plate library match the plate in use. If
necessary, re-calibrate the well depth
using the Auto feature according to
Incorrect aspiration parameters:
•
96-well plates require crosswise aspiration
to achieve minimal residual volumes. If
necessary, change the aspirate mode to
CrossWise.
•
Aspirate dwell time and rate might have to
be increased. See
•
Aspirate probe height should be set at
0.0 mm to 0.2 mm for minimal residual
volumes. See
Note:
If aspiration problems persist,
follow the Aspirate Testing Procedure that
is part of the instrument’s Performance
Qualification. If you do not have this
procedure, please contact Technical
Support.
