An automatic chemical analyzer including a reaction turntable having a plurality of reaction vessels arranged along a periphery thereof, a sample turntable having a plurality of sample vessels arranged along the periphery thereof, a reagent turntable having a plurality of reagent bottles in which different kinds of reagents are contained, a sample delivery mechanism for delivering a given amount of a sample into a reaction vessel, and a reagent delivery mechanism for delivering a given amount of a reagent into the sample to form a test liquid in the reaction vessel. The reagent delivery mechanism has a nozzle which can be moved between a reagent sucking position above a reagent bottle and a reagent discharging position above a reaction vessel; a plurality of detachable probes which are arranged in respective reagent bottles in such a manner that the tip of the nozzle can be inserted into a probe in a reagent bottle at the reagent sucking position; a syringe connected to the nozzle for sucking a given amount of a reagent into the probe coupled with the nozzle; and a probe removing mechanism for removing the probe from the tip of the nozzle after the reagent has been discharged into the reaction vessel and the probe has been returned into the reagent bottle from which the probe was picked-up by the nozzle.
