Vapor Pressure Measurement

A reliable method to determine osmolality.

Osmolality (Vapor Pressure) Testing

Vapor pressure osmometry is suitable for many fluids in biology and medicine in which water is the solvent. The vapor pressure method determines osmolality at room temperature with the sample in natural equilibrium. (This precludes cryoscopic artifacts due to high viscosity, suspended particles, or other conditions that can interfere with freezing point determinations, giving vapor pressure osmolality tests a broad range of reliable applications.) Osmolality is a stability indicating analysis and is recommended to be included in stability testing protocols for applicable products by The Osmolality Lab.
