Cobb Water absorption tester 61-PPT108 measures water absorption of sized paper, paperboard, and corrugated paper using the Cobb method. It features a (10 ± 0.5) kg metal roller and an inner cylinder area with 50 mm height for testing samples up to 125 mm diameter. Designed for absorbency papers in the 200 to 250 g/m² range, it delivers an absorbency speed of 75 mm/10 min under standard conditions. The overturn structure ensures ease of operation, suitable for quality control laboratories in packaging, pulp and paper, and material testing facilities requiring precise moisture resistance evaluation.Lab Expo

Lab Expo Paper Testing Instruments are used for strength, thickness, smoothness, tearing, bursting, compression, whiteness, water absorption, and tensile analysis of paper, pulp, carton, and corrugated board materials. Systems support measuring ranges up to 6000 kPa bursting pressure, 50 kN compression force, 16000 mN tearing capacity, and 1000 N tensile testing with high-resolution digital measurement. Units integrate air permeability, stiffness, folding endurance, friction, chromaticity, and ply bond testing for paper manufacturing, packaging inspection, and quality control applications.
