Absorbency-testing device is used for determining the absorption of liquid mediums, by paper from the top and bottom sides within a predetermined time.
The IGT Cobb tester is an absorbency-testing device used to determine the absorption of liquids, such as water, aqueous solutions, oils, varnishes and others, by paper, paperboard and corrugated board within an accurately, predetermined time, in accordance with ISO 535, Scan P-37:77 Scan P12, Tappi 441 and Fefco nr. 7.
There are different types of Cobb testers available:
- for determinations on thin substrates like paper and light paper board. A special version is available for light structured papers (e.g. tissue), which can also be used for paper and board
- for determinations on substrates up to 15 mm thickness, like massive board or corrugated board
- for determinations on plaster board construction panels up to 22 mm thickness
- as the standard version with the additional option to measure the absorption curve until the liquid passed through the substrate
