ENTRIFUGE
The disposable bowl is spun by the Centrifuge (Figure 2-11 and 2-12) to separate
anticoagulated whole blood into its various components.
The Centrifuge operates in a range of 3,000 to 7,000 revolutions per minute
(rpm). The most appropriate Centrifuge speed has been programmed for each
protocol. Chapter 3, Disposables, explains how blood is separated in the spin-
ning Centrifuge bowl.
There are two different types of centrifuge used in the MCS+ Systems. The cen-
trifuge that is installed in your MCS+ System may utilize a mechanical system or
a vacuum system to secure the bowl base during use. A “Mechanical Centrifuge”
uses mechanical clips to secure the bowl base, while a “Vacuum Centrifuge”
uses a vacuum system to secure the bowl base. The type of centrifuge used does
not affect the performance of the MCS+ device.
The mechanical centrifuge is easily distinguished from the vacuum centrifuge.
The mechanical centrifuge cover latch mechanism only requires a one-quarter
turn and a downward push to unlock the cover halves. The mechanical centri-
fuge also features six mechanical clips on the centrifuge chuck which secure the
bowl base as the bowl is snapped into place.
The vacuum centrifuge cover latch mechanism requires several turns before the
cover halves can be separated. The vacuum centrifuge also has an “L” shaped
gasket on the centrifuge chuck to assist the vacuum system in securing the bowl
base into place.
Warning! The silicone grease used in vacuum centrifuges
should never be applied to a mechanical centrifuge. Do not
grease any part of the mechanical centrifuge. If grease has been
applied to the mechanical chuck, contact Haemonetics Field
Service immediately.
Mechanical
Chuck
The bowl is held in the Mechanical Centrifuge by six mechanical clips in the
chuck. No tools are necessary to load the bowl. To load the bowl:
1. Center the bowl.
2. Push the bowl down until the bowl base snaps into place.
3. Swing the cover down, then squeeze the cover closed until the cover latch
snaps up.
4. Lock the cover switch by turning the cover latch knob clockwise.
