P/N 85213-30, Manual revision: B
Using a vacuum
centrifuge chuck
If the MCS+ device contains a vacuum chuck, a vacuum force will be created
between the base of the bowl and the chuck to hold the bowl in place. When
installing a bowl, the operator should exert a downward pressure on the head of
the bowl and ensure that the bowl is completely seated. The bowl will be
completely secured once the operator has locked the centrifuge lid.
To remove a bowl at the end of a procedure, the operator should simply pull
upward on the bowl until the vacuum force is disrupted. The bowl can then be
lifted out of the centrifuge well.

Caution: If any residual vacuum force remains and the operator cannot remove
the bowl using this technique, the manual vacuum release button can be used
(refer to Manual vacuum release button in Chapter 2). However, the operator
should not use this mechanism during routine MCS+ function, as this could dam-
age the bowl and/or centrifuge components.
