Overview
The Fungilab CV003-003 Capillary Viscometer is a precision measuring instrument based on the Ubbelohde Viscometer principle for the determination of the kinematic viscosity of liquids. The model is Ubbelohde ASTM size 0B and the viscosity measurement range is 1 to 5cSt.
Features
1. Adopts Usain Viscometer design and meets ASTM standards
2. Accurate measurement of viscosity range 1~ 5cSt
3. Suitable for a variety of liquid viscosity determination
4. Widely used in laboratories in various industries
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, use a liquid with known kinematic viscosity as a standard, measure the time it takes to flow out of the Capillary Viscometer, and then measure the time it takes for the sample to flow out of the same Viscometer, and calculate the viscosity of the sample.
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 with known kinematic viscosity
2. Time measurement of standard liquid from Capillary Viscometer
3. Prepare the sample to be tested
4. Time measurement of specimen outflow from the same Capillary Viscometer
5. Calculate the sample viscosity based on the outflow time
Notice
• Make sure the liquid completely wetting the capillary wall
Maintain a constant measurement temperature
• Check the cleanliness of the Viscometer before use
• Strictly follow the operation steps for measurement
• Select the model with the appropriate viscosity range for testing
