Overview
The Fungilab CV003-004 Capillary Viscometer is a precision instrument for the measurement of kinematic viscosity of liquids, designed in the Ubbelohde ASTM size 1 specification for liquids in the viscosity range of 2 to 10 cSt.
Features
1. Ubbelohde ASTM standard specification
2. Accurate measurement of 2~ 10cSt viscosity range
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. Measurement of the time for the sample to be tested to flow out of the same Viscometer
4. Calculate the kinematic viscosity of the sample according to the outflow time
Notice
• Make sure the liquid completely wetting the capillary wall
Maintain a constant measurement temperature
• Need to calibrate the instrument before use
• Strictly follow the operation steps to perform the measurement
