Overview
The Fungilab CV003-002 Capillary Viscometer uses the Ubbelohde ASTM size 0C specification and has a viscosity measurement range of 0.6 to 3cSt. The instrument is based on the principle of liquid flow in capillary tubing and is widely used for accurate viscosity determination of various liquids.
Features
1. Ubbelohde ASTM standard design
2. Accurate measurement of 0.6~ 3cSt viscosity range
3. Suitable for testing a variety of liquid samples
4. Simple structure and convenient operation
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 the liquid with known kinematic viscosity as the 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. Measurement time based on the sample viscosity
Notice
• Ensure that the capillary tubing is completely wet
Maintain a constant test temperature
• Make sure Viscometer is clean and pollution-free before use
• Strictly follow the standard operating procedures for measurement
