Changing the Bravo head
20 Bravo Platform Quick Guide
To install a Bravo liquid-handling head:
1 Make sure that the Bravo Platform is turned off and that the Bravo head mount is in
its home position, which is centered above deck location 5.
2 While the head remains seated in the head stand, pull out and twist the two head-
retainer pins one-quarter turn so that they remain retracted.
3 Remove the head from the stand as follows:
• Disposable-tip heads. Rest the bottom of the stand on a clean, dry surface.
Slide the head out of the stand as the following figure shows, so that the
barrels are facing down.
• Pin Tools. Ensure that the top of the head is resting on a clean, stable surface
so that the pins are facing up. Slide the stand off of the head.
4 With your left hand, firmly grip the left side of the head. Place your right hand under
the flat area just to the left of the array to support the weight of the head.
5 While supporting the head with your hands, slide the head onto the Bravo head
mount. Press the head firmly into place to ensure the head is plugged into the
connector receptacle on the head mount. You should hear the click when the
retaining pins snap into place.
