Cobb Tester / Cobb Sizing Tester
Manufactured by Techlab Systems
Cobb testers are widely used across the paper, board, printing, and converting industries to determine the amount of water absorbed by the sample over a given time period (typically 60 or 180 seconds).
The water absorbed is quoted in g/m², while the absorbency of the material can have a significant effect on the performance and printability of water-based adhesives.
This strong cobb tester has a 10 kg weight stainless steel roller and is spring loaded for quick and easy clamping of the sample, ensuring fast, repeatable testing.
