Overview
Fungilab CV003-006 is a Capillary Viscometer, model Ubbelohde ASTM size 1B, with a viscosity measurement range of 10 to 50 cSt. It is based on the principle of liquid flow in capillary tubing for viscosity determination and is widely used in various industrial and research fields.
Features
1. Ubbelohde ASTM standard design to ensure measurement accuracy.
2. Viscosity ranges from 10 to 50 cSt, suitable for medium viscosity liquids.
3. Simple structure, easy to operate, suitable for laboratory and industrial environments.
Principle
At a certain temperature, when the liquid flows in an upright capillary tubing in a state of complete wetting of the tube wall, its kinematic viscosity is proportional to the flow time. When measuring, the outflow time of the standard liquid with known kinematic viscosity is first measured, and then the outflow time of the sample from the same Viscometer is measured, and the viscosity of the sample is calculated.
Applications
Petroleum, chemical industry, light industry, electromechanical, national defense, transportation, coal, metallurgy, food, paper, Spinning & weaving, scientific research, institutions of higher learning
Steps
1. Prepare a standard liquid of known kinematic viscosity.
2. Fill the standard liquid into the Capillary Viscometer and measure its outflow time.
3. Clean the Viscometer and load the sample to be tested.
4. Measurement of sample outflow time from the same Viscometer.
5. Calculate the sample viscosity according to the standard liquid and the sample outflow time.
Notice
• Make sure the liquid completely wetting the capillary wall.
• Before measurement, it must be carried out at a constant temperature.
• Clean the Viscometer immediately after use to prevent residues from affecting the next measurement.
