The DSR allows product designers to develop toothpaste with the best uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder placed in between two parallel plates concerning the size of a quarter. Among the plates relocations and the equipment determines the viscoelastic buildings of the asphalt.
