The Vapor Pressure Osmometer K-7000 is used to determine the total osmolality of biological liquids. In addition, molecular masses of polymers can be determined in aqueous or organic solvents. The instrument is optimally supported by the software EuroOsmo®, which simplifies management of methods and measuring curves for easy data evaluation.
