Two of the vessels contain this fluid. The interior of these vessels is coated with surface modifier FC-723 to produce a desired contact angle. Distilled water is used in the other two containers, which are not coated. The fluids are lightly dyed in order to enhance visibility of the fluid interface. Up to 60 minutes are required for each vessel when tested independently.
Less time is necessary when the vessels are tested sequentially.
To begin the experiment,the crew member unstows a labjack, video camers, multi-use arm and clamp, and the ICE vessel to be tested. The Glovebox power is switched on and the ICE vessel is placed on the labjack. One video camera is mounted to the front door of the Glovebox, and the other is secured by the multi-use arm, directed down from the top. The field of view for the cameras is centered on the bulge portion of the exotic container. Iternative adjustments of the cameras and vessel are necessary to center the field properly for both cameras.
