Apparatus for centrifugally separating a sample

摘要

A shaft for centrifugally separating a sample includes a first shaft element having a first end taper portion and a middle straight portion, and a second shaft element having a second end taper portion. The first shaft element and the second shaft element are coupled and rotate in opposite directions. An adapter having a ring is mounted on the rotating first taper portion of the shaft by the ring. The adapter receives a sample tube and the adapter and the sample tube are transported forward on the first end taper portion of the shaft. The adapter and the sample tube are sent to the middle straight portion of the shaft and the sample is centrifugally separated in the middle straight portion of the shaft. The adapter and the sample tube are sent to the second taper portion of the shaft and disengaged from the second end taper portion of the shaft. The adapter and the sample tube are automatically mounted on the shaft, and the sample is centrifugally separated on the shaft, after which the adapter and the sample tube are automatically disengaged from the shaft.
