2.5.2 Aspirating
Positions
To ensure that all the wash solution is correctly aspirated out of the wells, the
manifold can be positioned so that the aspirating needles are correctly positioned
in the wells for both round or
V
shaped and flat bottom microplates.
All settings are defined in the Plate Type setting option of the Adjust menu.
With round or
V
shaped bottom wells, the aspirating needles are placed in the
middle of the wells.
