Abstract
To provide a technology capable of stabilizing droplets. Provided is a particle isolation device or the like including: a vibration unit that applies vibration to a fluid containing sheath liquid by supplying a driving voltage based on each of a plurality of frequencies; an imaging unit that acquires, at a position where the fluid is formed into droplets through the vibration, an image of the fluid and each of the droplets; a liquid temperature control unit that controls a liquid temperature of the sheath liquid; and a frequency control unit that acquires data regarding a state of the droplet at each of the frequencies per liquid temperature of the sheath liquid from the image captured by the imaging unit, and controls the frequency of the driving voltage on the basis of a variation in the data accompanying a change in the liquid temperature of the sheath liquid.
