Vapor pressure measurement is the best method of determining osmolality, and the thermodynamic limitations of vapor pressure osmometry are least restrictive. For these reasons, vapor pressure osmometry is superior for most fluids in biology and medicine in which water is the solvent.
LeanGene offers the Vapro® Vapor Pressure Osmometer from ELITechGroup that can be used to determine the osmolality in any type of sample: fluids, viscous, and even tissue, giving the Vapro® great versatility in clinical medicine or biomedical research applications.
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 Vapro® a much broader range of error-free applications.
The fundamental advantages of Vapro® have been enhanced with automatic thermocouple cleaning and mechanized sample slide operations, making osmolality measurements with the Vapro® the easiest and most user-friendly available. The Vapro® programming includes robust self-diagnostics for complete monitoring of osmometer functions.
The Vapro® includes computer and printer interface capability. It requires a sample volume of only 10 microliters. Osmolality is displayed in 90 seconds.
