Overview
Fungilab CV003-108 is a Capillary Viscometer, model Ubbelohde DIN size IIIc, for the measurement of the kinematic viscosity of liquids. The instrument is designed based on the principle of capillary method and can accurately determine the viscosity value of liquids at a specific temperature.
Features
1. Ubbelohde DIN standard design to ensure measurement accuracy
2. The viscosity measurement range covers 600~ 3000 cSt, suitable for medium viscosity liquids
3. Widely applicable to a variety of industries and scientific research fields
4. Measurement principle based on mature capillary method
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. 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
• Make sure the liquid completely wetting the capillary wall
• The measurement process needs to be carried out at a constant temperature
• Instruments should be calibrated before use
• Strictly follow the operation steps to perform the measurement
• Pay attention to keep the instrument clean
