Introduction and Overview:
This project is to be designed on request from the Pharmacy research department at the University of Connecticut. In pharmaceutical settings, it is important to accurately determine the viscosity of potential drugs. However, a vast majority of drugs in clinical trials are expensive to produce and thus significantly increase the cost of research. In order to minimize these costs, it is desirable to produce a device that can accurately measure the viscosity based on a smaller sample size. Thus, the apparatus to be constructed should utilize a range of frequencies with a minute volume of sample product in order to determine the rheological properties of that sample.
