Overview
Fungilab CV003-105 is a Capillary Viscometer, model Ubbelohde DIN size II, with a viscosity measurement range of 20 to 100cSt. The instrument is designed based on the principle of liquid flow in capillary tubing and is used to accurately determine the kinematic viscosity of liquids.
Features
1. Ubbelohde DIN standard design to ensure measurement accuracy
2.The viscosity measurement range covers 20~ 100cSt
3. Suitable for viscosity determination of various liquid samples
4. Simple structure and easy 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 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. Use a standard liquid of known kinematic viscosity to calibrate and measure its time from capillary tubing
2. Load the sample to be tested into the same Capillary Viscometer
3. measurement of time from capillary tubing
4. Calculate the kinematic 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
• The measurement process needs to be carried out at a constant temperature
• Use a standard liquid calibrating instrument before use
Keep capillary tubing clean to avoid clogging
• Select the applicable model strictly according to the viscosity range
