The DSR allows item programmers to create toothpaste with the right consistency so that it can be pressed from a tube but not drop off the toothbrush. The DSR tests binder put between 2 parallel plates concerning the size of a quarter. Among home plates relocations and the machine determines the viscoelastic residential properties of the asphalt.
