The DSR enables product programmers to create toothpaste with the best consistency so that it can be pressed from a tube but not fall off the tooth brush. The DSR examinations binder placed in between 2 identical plates about the size of a quarter. Among the plates actions and the maker measures the viscoelastic residential properties of the asphalt.
