Provided is a temperature control system applied to an apparatus for analyzing a sample using a pipette nozzle and a reaction container, including a pipette tip temperature controller that heats a pipette tip which is fitted on the pipette nozzle and aspirates or discharges liquid and a reaction container temperature controller that heats the reaction container. The pipette tip temperature controller heats, in a concentrated manner, at least a distal end portion of the pipette tip of the pipette nozzle located at a predetermined heating position with hot air emitted from a heat source and is configured such that a distal end is capable of arriving at the reaction container by lowering the pipette nozzle from the heating position.

Temperature control system

A pipette tip leading end detection device for detecting that a leading end of a pipette tip is close to a reference surface set to a reaction vessel includes a pipette nozzle, pump, nozzle driver, pressure sensor that detects a pressure generated between the pipette tip and pump, and hardware processor. The hardware processor obtains a determination value using an AD conversion value obtained from the pressure while the pipette nozzle is being lowered, and detects that the leading end of the pipette tip is close to the reference surface on the basis that the determination value is a threshold value or more. The determination value is a calculation value indicating a pressure change speed calculated from AD conversion values within a past certain time and the threshold value is a value larger than maximum noise.
