Title: Apparatus for measuring viscosity of liquids

Abstract: An improved apparatus is provided for measuring the viscosity of a liquid comprising a rotatable container means; means for rotating said container means at a desired speed; a freely rotatable member within said container means, said container means and said member defining a volume therebetween for receiving liquid to be measured; a third bath surrounding said container means for maintaining said container means at a desired constant temperature; means for measuring torque of said member when said volume is charged with liquid to be measured and said container means is rotated by said rotating means; and a bearing made from a material having a high thermal conductivity and located between and contacting said container means and said fluid bath to facilitate relative rotation therebetween.
