PURPOSE:To prevent the failure in drawing of supernatant liquid in a mechanism for dispensing the supernatant liquid of centrifugally separated sample by forming conducting parts between a guiding plate for the supernatant liquid and the opening ends of specimen tubes in such a way that when both come in contact with each other normally, both are electrically conducted. CONSTITUTION:A rack 9 contg. specimen tubes 10 contg. centrifugally separated precipitate 13 and supernatant liquid 14 is mounted on a gondola 6. The gondola is lifted to bring the guiding grooves 15 of a guiding plate 8 for supernatant liquid into contact with the opening parts of the tubes 10. An arm 2a is driven by a cylinder 2 to tilt the gondola 6 so that the liquid 14 is dispensed into the supernatant liquid tubes 12 in a rack 11. A conducting part 30 having discontinuous parts 32 is provided to the plate 8 in the arranging direction of the grooves 15, and conducting parts 31 are provided to the tubes 10 as well. Then whether the grooves 15 are in normal contact with the tubes 10 or not is detected by an electrical continuity detecting means. |
