Device Description:
The Cobb-Unger Oil or Water Absorption Tester is different to a regular Cobb tester due to its pivotable liquid container, with a quick latch cover, which can be removed for easy cleaning. The integrated couching mechanism consists of the roll and the couching plate and allows effortless couching. The unit includes a digital stop watch for time measurement which starts automatically when the liquid container is rotated.
Test Description:
The liquid container is filled with oil or water and is placed in the unit. A weighed sample is placed over the container and the cover is closed. A handle on the side of the unit is used to rotate the container with the clamped sample. The pre-set time on the stopwatch begins to count down. When the time has elapsed, a signal tone calls to activate the container in the start position. The sheet is removed and placed on the couching plate. It is then covered with a blotter and couched by pulling and pushing on the couching plate. The blotter is removed and the sample is weighed again to determine the sample’s absorbency.
