ABSTRACT:
An automatic sample pretreatment device is provided which is capable of conducting a series of treatments or reactions from pretreatment to measurement automatically in a short time by employing a separate reaction system from the reaction system for measurement. The automatic sample pretreatment device comprises a sample rack, a pretreatment vessel and a measurement vessel, a liquid dispenser, a first vessel-transfer apparatus having a vessel holder for holding and transferring the vessels, a pretreatment vessel feeding apparatus for feeding the pretreatment vessel to the vessel holder of the first vessel transfer apparatus, a measurement vessel feeding apparatus for feeding the measurement vessel to the vessel holder of the first vessel-transfer apparatus, a vessel discarding hole for discarding the vessel after use, a second vessel-transfer device for transferring the used vessel held at the vessel holder of the first vessel-transfer apparatus to the vessel discarding hole, an incubator equipped with a measurement device for measuring a sample, and a third vessel-transfer device for transferring the vessel held by the vessel holder of the first vessel-transfer apparatus to the incubator.
