The department has a Brookfield RVDV-E Viscometer which is occasionally used in the teaching lab, this is a rotational viscometer used for medium viscosity materials.  Typical examples of which include creams, food and paints.  It measures the torque required to rotate a spindle in a fluid. The spindle is driven by a motor through a calibrated spring and the deflection of the spring results in a torque which is indicated on a digital display. It uses a multiple speed transmission and has interchangeable spindles to measure a variety of viscosity ranges.
