Changing the Bravo head
About this topic
Use the procedures in this topic to uninstall a liquid-handling head, install a different
head, and adjust the corresponding settings in the VWorks software.
Before you start
AssayMAP Bravo Platform only. To prevent potential injury from exposure to
chemical spills, ensure that you empty the syringes before uninstalling the Bravo
96AM Head. For instructions, see “Uninstalling the Bravo 96AM Head” on page 209.
Put on gloves to protect your hands from potential exposure to any residual
contaminants.
Always turn off the Bravo Platform before installing or uninstalling a liquid-
handling head. Failure to do so can damage the head electronics.
If a head is being used for the first time, make sure you have a profile specifically for
that head. If necessary, create a new profile before starting the following procedure.
For details, see “Creating and managing profiles” on page 26.
If disposable tips are loaded on the currently installed head, use Diagnostics to
dispense any liquid and remove the tips before removing the head. For instructions,
see “Performing a task using Bravo Diagnostics” on page 100.
Make sure that the head mount is in its home position above deck location 5. If
necessary, click the Jog/Teach tab in Diagnostics, and then click Home XYZ to
reposition the head mount.
If you are changing the currently installed head for the same type of head and want
to edit the profile, you may use the Change head wizard. Otherwise, use the
following procedure.
Uninstalling the liquid-handling head
To uninstall the liquid-handling head:
1 Ensure that the Bravo Platform is turned off. Check that the power switch
located on the right side is set to off (o) and the status lights on the device front
are not lit.
