COBB Sizing Tester

Equipment to determine the water absorption capacity of paper and corrugated cardboard, featuring a quick clamping grip. The quick clamping system secures the sample by spring, ready for rapid, repeatable testing.

Key Features

• Quick spring-clamping system for fast sample loading.
• Standard sample test area: 100, 50, 25 or 10cm² (depending on model).
• Made of stainless steel.
• Soft rubber sealing gasket prevents lateral water seepage.

Applications

Widely used across the paper, board, printing and converting industries to determine the amount of water absorbed by a sample over a given time period (typically 60 or 180 seconds), quoted in g/m². Absorbency has a significant effect on the performance and printability of water-based adhesives. Suitable for corrugated board and solid board applications. Meets DIN 53132, EN 535:2014, FEFCO 7, ISO 535, NF Q-03-018, NF Q-03-035, SCAN P12 and TAPPI T441.
