  • The capillary viscometer is delivered complete with instrumentation, technical manual and practical work
  • The liquid we study the flow is placed in a thermostatted pressure vessel which is detachably connected to a capillary tube also thermostated
  • Ability to continuously vary the pressure of pressurization of the chamber and the temperature of the liquid being examined continuously stirred to ensure its homogeneity
  • The capillary tube is also removable (two possible diameters provided)
  • The viscosity is determined from the travel time of the liquid in the capillary


  • Electricity: 230 V - 50/60 Hz
  • Compressed air: 1 mini bar
  • Length: 760 mm
  • Width: 560 mm
  • Height: 600 mm
  • Weight: 60 kg


From flow measurements and pressure drop in the capillary viscometer can:
  • to study the Poiseuille flow
  • to study a known viscosity liquid
  • accurately determine the radius of the capillary tubes
  • to measure the dynamic viscosity of a liquid and to study its variation as a function of temperature
  • to study the shear stresses in viscous fluids and friction forces on pipes in laminar regimes.


The apparatus is provided with the following instrumentation:
  • a manometer Ø160 Bourdon tube
  • a thermometer
  • a timer for measuring the time
  • two graduated pipettes
  • a thermostatic bath
  • magnetic stirrer
Capillary tubes: 0.2 mm and 0.4 mm - length 400 mm
Temperature scale: 90 ° C ± 0.5 ° C
Pressure scale: 0-1 bar
