A droplet measurement system is provided with: an imaging device placed to locate a tip part of a nozzle and the entire liquid hanging down from the nozzle within a field of view; an image generation unit that generates a plurality of images that capture the state in which droplets are dripping down from the nozzle based on image data output from the imaging device; a dripping detection unit that detects, from the plurality of images, a dripping-detected image in which the fact that a droplet has departed from the nozzle is detected; and a volume calculation unit that calculates the volume of the droplet based, at least, on an image-before-dripping, which is generated a predetermined number of frames before the dripping-detected image and capturing liquid hanging down from the nozzle and on a reference image that captures at least the tip part of the nozzle.

A pipetting system includes: a pipetting device; a pipetting container including a plurality of pipetting positions into each of which the pipetting device pipettes liquid; and a positional relation detector configured to detect a positional relation between a front-end position of a tip and each of the pipetting positions. The pipetting device includes circuitry configured to, when a pipetting switch that orders pipetting is turned on, on condition that the front-end position of the tip detected by the positional relation detector is located at one of pipetting positions that is indicated by a pipetting pattern set up in advance, allow pipetting corresponding to the pipetting pattern, and on condition that the front-end position of the tip detected by the positional relation detector does not correspond to a corresponding one of pipetting positions that is indicated by the pipetting pattern set up in advance, disallow the pipetting.
