Changing the Bravo head
Bravo Platform User Guide
2 Carefully remove the liquid-handling head and protective stand from the
packaging. While the head remains seated in the stand, pull out and twist the
two head-retainer pins one-quarter turn so that they remain retracted.
Do not rest the bottom of a liquid-handling head on any surface. Doing so can
damage the barrels, pins, or probes.
To prevent potential contamination, do not touch the liquid-handling head barrels,
tips, or probes with your hands.
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.
• Bravo 96AM Head. Ensure that the top of the head is resting on a clean,
stable surface so that the probes are facing up.
The probes of the AssayMAP Bravo 96AM Head are sharp and can scratch you if
they brush across your hand. A probe scratch can expose you to any
contaminants remaining on the probes. Wear gloves and use extreme caution to
avoid brushing against the probes.
Using both hands, carefully lift the stand off of the head while guiding the
stand’s side cutouts (1) off the head side tabs (2). Use care to avoid
touching the probes.
