GURLEY™ Cobb Sizing Testers have been manufactured by Gurley for over a half-century
Represent an economical and practical means of determining liquid absorptiveness or resilience of treated and untreated papers, boards, fabrics and other sheet materials.
The complete kit consists of the Gurley- Cobb test apparatus, its 10-kg roller and a supply of blotting paper.
The roller method is recommended to insure better consistency and reliability that can be obtained by manual blotting or rubbing the specimen.
Purpose of Test
Water absorptiveness of paper board or other materials is a function of various characteristics such as sizing, porosity, etc. The Gurley-Cobb sizing test can be used ...
The ACT 2600 Automatic Cobb Tester is an innovative method for understanding dynamic water absorption
The ACT 2600 tests a full 100 cm² area of sized paper or board as a function of time.
The test is done automatically so no weighing or blotting of the specimen is required
The length of the test is reduced to only a few seconds of loading the sample.
-Thwing-Albert is pleased to announce the introduction of the innovative ACT (Automatic Cobb Tester). The ACT applies water to a sized (non-bibulous) specimen surface during a preset test time (e.g. 60 seconds). As water is absorbed by the specimen, the water level inside the test chamber is reduced, which ...
