Osmolality
R. D. Laboratories, Inc. utilizes a Precision System Osmette A Automatic Osmometer to determine osmolality. Osmolality is a critical measurement for many isotonic solutions. The osmotic pressure is also important in determining whether a solution is hypo-osmotic, iso-osmotic or hyperosmotic. Formulation and design of some pharmaceutical preparations require accurate control of this physical property since it sometimes plays a critical role in diffusion of solutes or fluids through biological membranes.
