The time required for an air buble to rise is directly proportional to the viscosity of the liquid - the faster the bubble rises, the lower the viscosity. Gardco bubble viscometers come in lettered tubes A5 through Z10 in four different tube sets covering viscosity ranges from 0.05 to 1,000 stokes. ProductSiteLaunchDate : 2019-11-09T23:47:08.508Z
