Pharmaceutics B

Introduction

This course supports theory taught by applying some experimental work to determine the Colligative properties such as freezing point depression, osmotic pressure and preparation of isotonic solutions.

The course also contains experiments on the rheology and flow properties of liquids and semisolids, surface tension and interfacial phenomena.
