The DSR allows product programmers to develop toothpaste with the right uniformity so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR examinations binder positioned between 2 parallel plates about the dimension of a quarter. Among home plates steps and the device gauges the viscoelastic residential or commercial properties of the asphalt.
