SEALING MECHANISM
The MCS+ centrifuge contains a split, hinged lid (or cover) and a locking knob.
These components “seal” the system by:
!
Securing the contact of the disposable bowl with the centrifuge base.
!
Isolating the spinning bowl from the operator.
Centrifuge cover
The centrifuge lid, referred to as the cover, has tabs located on the rimmed
portion of each split side. The split halves are attached to the centrifuge rim by a
hinge. As the halves of the lid are lowered to meet the rim, the tabs must be firmly
pressed together in order to completely close the lid and provide a seal around
the stationary head of the disposable bowl.
The split halves of the lid are made from a durable, transparent material, allowing
the operator to observe changes in the bowl contents as the centrifuge spins.
Locking knob
The locking knob is positioned on the rim of the centrifuge well.
Two types of locking knobs exist among the MCS+ devices in use.
Figure 1-8, Locking knob (turn to open/close)
One style of knob requires a series of turns to lock or unlock the lid. Once the lid
has been fully closed, the knob should be turned in a clockwise direction to lock
the centrifuge and thus completely seal the system. The operator will be cued by
the MCS+ display screen.
To unlock the centrifuge, the operator should turn the knob in a counter-clock-
wise direction until the split halves can be separated, then lifted to open the lid.
