About This Product
Students set the vessel pressure and liquid temperature, collect the liquid that passes through the capillary in a measuring cylinder and time it, then work out viscosity from that single pressure reading and time interval. Changing the capillary or the temperature lets them investigate Poiseuille flow and how viscosity varies with temperature. Colleges and TVET centres in New Zealand, Mexico, Vietnam, Tajikistan and Kyrgyzstan can source the Capillary Tube Viscosimeter from Educational Lab Equipments.
Frequently Asked Questions
What temperature range does it cover?
From ambient up to 80 degrees C, stated to 0.5 degrees C. The vessel and the capillary tube are both thermostatically controlled, and a magnetic stirrer keeps the liquid temperature uniform.
Which capillary sizes are supplied?
Interchangeable capillary tubes of 0.2 mm and 0.4 mm diameter.
How is pressure measured?
With a mercury manometer covering 0 to 100 cm Hg; the vessel pressurisation can be varied continuously.
