Abstract
A nozzle device, comprising a nozzle body, a ball provided in the nozzle body and elastically deformable by compression, an aliquoting/dispensing tip having a barrel portion in which the nozzle body including the ball is inserted, and a ball compressing mechanism which is provided in the nozzle body, configured elastically to deform the ball by compression so that the diameter of the ball increases with the nozzle body including the ball inserted in the barrel portion of the aliquoting/dispensing tip, thereby pressing the ball airtightly against an inner peripheral surface of the barrel portion of the tip, when the tip is attached to the nozzle body, and configured to remove a compressive force from the ball so that the diameter of the ball is reduced, thereby separating the ball from the inner peripheral surface of the barrel portion of the tip, when the tip is detached from the nozzle body.
