ABSTRACT:
The present invention is a centrifuge bowl housing and cover latch suitable for use in a blood separation system. The housing is mounted on shock absorbers to minimize transmission of vibrations from the centrifuge. The housing is configured to retain spilled liquids, efficiently collect the spilled liquids, drain liquids away from the drive means, and drain liquids out of a drain port to a collection container. The housing has a transparent cover that opens to allow loading of centrifuge bowls into the housing. The cover is a shatter resistant material and when closed, seals the top of the housing, retaining blood components and flying pieces of a centrifuge bowl if the bowl breaks. The cover has a latch that prevents the centrifuge from spinning when the cover is open and prevents opening of the cover when the centrifuge is spinning.
