Analytical equipment, in which liquid substances in sample containers and reagent containers are delivered to reaction cells by a vertically movable probe. The sample containers and the reagent containers are supported on a rotatable metal plate. The metal plate is rotated to place one of the sample containers or reagent containers at a sample or reagent pipetting position. The probe transmits a high-frequency signal to detect a change in electrostatic capacitance between itself and the metal plate at a time the probe is put in contact with a liquid substance in the sample or reagent container. A spline shaft for moving the probe in a vertical direction has a detection plate, and a control signal is generated when the detection plate reaches a predetermined position. The generation of the high-frequency signal is stopped when the probe begins to make a descending motion until the control signal is generated, to reduce the adverse effect of disturbing waves on various parts.
