The DSR allows product programmers to develop toothpaste with the appropriate uniformity so that it can be pressed from a tube yet not drop off the tooth brush. The DSR tests binder positioned between two parallel plates concerning the dimension of a quarter. Among home plates relocations and the equipment determines the viscoelastic properties of the asphalt.
