Capillary viscometers can be classified into four types based on their structure and shape: Ubbelohde, Fischer, Heisei, and countercurrent. The viscosity of the samples they measure is kinematic viscosity. It has been widely used in petroleum, chemical, light industry, electromechanical, national defense, transportation, coal, metallurgy and medicine, food, papermaking, textile, scientific research, higher education institutions and other units. Proper use of capillary viscometers is crucial for ensuring product quality and accuracy of scientific research data.
Washing and drying:
Before use, the viscometer must be cleaned thoroughly. Generally, it is washed repeatedly with a solvent that can dissolve the residue inside the viscometer, then washed with alcohol or gasoline, and then washed with fuming sulfuric acid or potassium dichromate solution for 2-3 hours. Finally, it is rinsed with tap water and distilled water, placed in an oven, heated to around 150 ℃, or inverted at natural temperature for several days and evaporated until dry.
