PROBLEM TO BE SOLVED: To simplify and accelerate the measuring work of a test tube. SOLUTION: A work station has a feeder 1 for a test tube rack 7, and a test tube holder 7 has a balance 17 for measuring the weights of individual test tubes 6 in a step of measuring before and after pickup of each tube 6 about each tube 6 in each case. In each case the pickup work uses a gripper 23 of a conveyer 3, the conveyer 3 distributes the tubes 6 to test tube buckets 22 so as to form pairs of buckets having approximately the same weight, the buckets 22 are picked up and put in a centrifuge 2 by the help of a receptor 27 removed from the holder gripped with the gripper 23, the buckets 22 are, after centrifuging, picked up with the receptor 27 set in the holder, and the individual tubes 6 are picked up from the buckets 22 and disposed on a carrier 5 of the conveyer 4. |
