Abstract: Apparatus and method for removing bubbles from a discrete sample of a temperature-sensitive liquid, particularly a photographic emulsion. A container having a bottom and side walls defines a sample area containing the liquid to be sampled and is made of a substantially acoustically transparent material. The container is removably mounted to a receptacle such that the bottom and at least a portion of the side walls are immersed in a fluid bath. The fluid bath is heated to maintain the liquid at a predetermined temperature greater than ambient temperature. An ultrasonic device spaced from the container directs ultrasonic waves through the fluid toward the bottom of the container to degas the liquid.
