Changing the Bravo head
About this topic
The procedure for changing the head that is mounted on the Bravo Platform is basically the same for the different types of heads, including disposable- tip heads, fixed- tip heads, and pin tools. Use the procedures in this topic to remove a mounted head, install a different head, and adjust the corresponding settings in the VWorks software.
Before you begin
WARNING
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 192 .
IMPORTANT
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 28 .
• If there are disposable tips on the currently installed head, use the Tips Off command in Bravo Diagnostics to remove the tips before removing the head.
• Make sure that the head mount is in its home position above deck location 5.
If the head mount is not in the home, click the Jog/Teach tab in Bravo
Diagnostics, and then click Home XYZ to reposition the head mount.
