Overview
Fungilab CV003-001 is a Capillary Viscometer with a viscosity measurement range of 0.3 to 1 cSt in the Ubbelohde ASTM size 0 specification. The instrument is designed based on the principle of liquid flow in capillary tubing and is suitable for accurate determination of liquid kinematic viscosity.
Features
1. Ubbelohde ASTM standard design to ensure measurement accuracy
2. Covering a viscosity range of 0.3 to 1 cSt, suitable for low viscosity liquids
3. Simple and reliable operation based on capillary tubing flow principle
4. Widely compatible with a variety of industry application requirements
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, first 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. 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 viscosity of the sample according to the outflow time of the standard liquid and the sample
Notice
• Make sure the liquid completely wetting the capillary wall
• Control the temperature during the measurement process
• Wash Viscometer before use to avoid contamination
• Perform measurements in strict accordance with standard operating procedures
