Probe for channel A1 in the Bravo 96AM Head
When fewer than 96 cartridges are mounted on the head, careful planning of the deck
layout and the robot moves is required to prevent potential collisions between the
remaining bare probes and the items on the Bravo deck. A mounted cartridge extends
only 9 mm beyond the tip of a bare probe, as the following figure shows.

9 mm
Because the distance between the tip of the bare probe and a mounted cartridge is
relatively small, you must ensure the following:
•
The depth at which the cartridges enter the wells is no more than 9 mm.
•
When doing partial-plate operations where the head is offset horizontally from the
target deck location (not centered over the platepad), ensure sufficient vertical
clearance for the unused probes:
–
Target deck location. If the labware has deep wells and the head goes down too
far, a collision between the unused probes and the perimeter of the labware can
occur.
–
Adjacent deck location. If a labware or other object at the adjacent location is
taller than the labware at the target location, a collision between the unused
probes and the tall object or labware can occur.
Note: No horizontal offset of the head is required for partial-plate operations where the
selection of channels in the head aligns with the labware well selection. For example,
probe A1 enters well A1.
The following figures show examples of partial-plate operations where the head is
offset horizontally from the target deck location. In this example, cartridges are
mounted on the probes in columns 1 and 2. To access the wells in columns 11 and 12
of the labware at deck location 7, the head is offset over deck location 8.
