Overview
Fungilab CV003-114 is a Ubbelohde DIN size IVa Capillary Viscometer 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 of liquids in the range of 10000 to 50000cSt.
Features
1. Ubbelohde DIN standard design
2. Wide viscosity measurement range covering 10000~ 50000cSt
3. Suitable for viscosity determination of various liquid samples
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. During the measurement, the standard liquid with known kinematic viscosity is used to measure the time it flows out of the Capillary Viscometer, and then the time it flows out of the sample from the same Viscometer is measured. The viscosity value of the sample can be obtained by calculation.
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
Maintain a constant measurement temperature
• Make sure Viscometer is clean and pollution-free before use
• Strictly follow the standard operating procedures for measurement
