Abstract: This application relates to a measurement system for measuring a behavior of an ejection liquid, which is ejected into an object from an ejection device, within the object. The system includes a container part formed of a resin material. The system also includes an imaging device disposed to image, across the object, a tip surface of the container part having an ejection port formed therein and being in contact with the object from a back side of the object in a predetermined state in which the ejection port is positioned from a front side of the object. The system further includes a first emission device that emits first near infrared light to the tip surface. In such a configuration, the behavior of the ejection liquid when the ejection liquid is ejected into the object from the ejection device can be imaged and measured by the imaging device.

Abstract: This application relates to an ultra fine bubble production apparatus for producing ultra fine bubbles. The apparatus may include a container portion including a liquid and a gas, and a drive portion for pressurization in the container portion. In the pressurization, the time required for the pressure to reach the maximum pressure from the start of the pressurization can be 2.0 milliseconds or less, and the maximum pressure can be 4.00 MPa or more.
