The patented split cell design of the MiniVisc 3000 viscometers allows for the measurement of kinematic viscosity with just a few drops (60 µL) of oil. When the split cell is closed, the central ...

Since 1944, physicists at Trinity College in Dublin have been trying to measure the viscosity of pitch tar, a polymer seemingly solid at room temperature, and witness it dripping from a funnel.

Pitch-drop experiments involve heating a sample of pitch and pouring it into a sealed glass funnel. The pitch is ... the mechanics of the break, and the viscosity of the pitch”.
