Cobb-Unger Oil- & Waster Absorption Tester

Product line: S95333

For determination of oil or water absorption. The Cobb-Unger oil or water absorption tester is different to a regular Cobb tester due to its rotatable liquid container, with a quick latch cover, which can be removed for easy cleaning. The integrated couching mechanism consists of a roll and couching plate, allowing effortless couching. The unit includes a digital stopwatch, for time measurements, that starts automatically when the liquid container is rotated.

Test description

The liquid container is filled with oil and water and 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 clamped sample, and the preset time on the stopwatch begins to count down. When this time has elapsed, a signal noise is heard and the container can be rotated to the start position. The wet 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 weighed again to determine the sample’s absorbency.
