The DSR allows product developers to produce toothpaste with the best consistency so that it can be squeezed from a tube but not drop off the tooth brush. The DSR examinations binder placed in between two parallel plates concerning the size of a quarter. Among the plates actions and the equipment determines the viscoelastic buildings of the asphalt.
