Cobb Sizing Tester About

Cobb Tester determines water absorption/penetration (Cobb Value) of paper, paper board, corrugated fiber board and other sheet materials. Cobb value is the Quantity of water in mgs absorbed by surface of 100 cm2 of the specimen on one side only in a specified time under a specified head of water. It measures the weight increase of a sample exposed to water for a given time. The container mounted on a stand and filled with the specified amount of water that can be turned upside down to contact with water with a knob. After the test time has elapsed it is turned back and sample taken for analysis. The filled water can be used several times before it replenished. The lid is clamping by way of spring-loaded finger grips. The Test consists of a Test Apparatus, Roller & Blotting Paper.

High-Precision Sizing for Laboratory Needs

Engineered for dependable and repeatable results, the Cobb Sizing Tester is built from corrosion-resistant stainless steel and designed to handle samples up to 0.25 inches thick. Its rectangular base provides stable support for the cylindrical components, ensuring accurate and safe operations.

Effortless Operation and Versatile Applications

With a quick-release clamp mechanism and manual rolling system, this equipment allows users to test water absorbency quickly and efficiently. Its 100 ml measuring cylinder and user-oriented manual facilitate easy usage, making it ideal for laboratories, research, and quality control settings.

FAQ's of Cobb Sizing Tester:

Q: How do you use the Cobb Sizing Tester for evaluating paper water absorbency?

A: To use the Cobb Sizing Tester, place the paper sample within the test area, secure it using the quick-release stainless steel clamps, add the required volume of water using the provided measuring cylinder, and use a manual stopwatch to time the test. After the timed interval, roll the 10 kg roller over the sample to remove excess water, then measure the absorbed amount to determine water absorbency.

Q: What are the benefits of using a manual Cobb Sizing Tester in a laboratory?

A: The manual operation eliminates the need for external power, ensuring reliable performance even in basic lab setups. The precise measurement system, durable construction, and corrosion-resistant materials yield long-lasting, accurate results, making it a trusted choice for quality control and research.

Q: When should you perform a Cobb Sizing Test on paper or board materials?

A: You should perform a Cobb Sizing Test whenever assessing the water absorbency characteristics of paper, cardboard, or similar materials is necessary-especially for quality assurance, material comparison, or compliance with industry standards.

Q: Where is the Cobb Sizing Tester typically used?

A: The Cobb Sizing Tester is commonly used in laboratories within the paper and packaging industries, research institutions, and quality control departments that require precise measurement of water absorbency for various materials.

Q: What process does the Cobb Sizing Tester follow for determining absorbency?

A: The standard process involves placing the sample on the testing plate, clamping it securely, introducing a measured amount of water, timing its exposure, then removing excess water with the roller. The absorbed water is quantified to evaluate the sample's absorbency.

Q: What accessories are included with the Cobb Sizing Tester for accurate testing?

A: The equipment comes with a 100 ml measuring cylinder, a rubber gasket for secure sample placement, and a user manual to guide proper operation-all essential for achieving accurate and repeatable test results.
