Inclination type dispensing mechanism for supernatant liquid

Abstract

Abstract PURPOSE:To prevent the falling of specimen tubes and to dispense supernatant liquid surely in a mechanism for dispensing the supernatant liquid of centrifugally separated sample by providing a guiding plate which guides the top end edge of a rack for containing of the specimen tubes and prohibits the inclination thereof. CONSTITUTION:A rack 9 contg. specimen tubes 10 contg. centrifugally separated precipitate 13 and supernatant liquid 14 is mounted on a gondola 6 and the gondola 6 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 rack guiding plate 30 fixed to a rack support 28 is provided to the gondola 6 to prevent the falling of the tubes 11 in the rack 9 by means of a sloped guiding surface 31 which guides the top end edges of the racks 9 lifted by the gondola 6 and a linear guiding part 32.
