COBB Water Absorption Tester

For determination of water absorption. The Cobb tester measures the amount of liquid that has been absorbed by paper or cardboard within a certain time. The Cobb has a bottom area of 100cm² but is also available with inserts for smaller areas.

TEST DESCRIPTION

A weighed sample is clamped in the Cobb tester. 100ml of water (correspondingly less for smaller cylinders) are added to the cylinder. With COBB60, the water is left in the container for 45 seconds and then emptied away. The wet sheet is now removed and placed on the flat surface. Cover the sample with a Cobb blotter and gauze it with the roll. The sheet is then removed and reweighed. The COBB value is determined.
