  • Device for detecting leading end of pipette tip, and storage medium storing program for detecting leading end of pipette tip
    Patent number: 11204363
    Abstract: 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.
