Osmometer

Semi-Micro Osmometer K-7400 The Semi-Micro Osmometer enables freezing point depression to be measured. Additionally, the total osmolality of physiological and biological liquids, transfusions, and infusion solutions can be measured. The measurement run is completely automated after the sample is injected. The instrument is equipped with an air cooling and an integrated microprocessor. The measuring head is available in two versions, one for glass vials and one for plastic vials with attached cap. A printer can be optionally ordered.

Osmometer

Vapor pressure osmometer K-7000 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.

EuroOsmo 7000 The EuroOsmo® software is a user-friendly software for system control and data acquisition of the Vapor Pressure Osmometer K-7000 by KNAUER. Via a graphic set up, three different operating modes can be selected: osmomality determination, molecular weight determination <500 g/mol, or molecular weight determination >500 g/mol. Besides visualizing the measuring curve, a detailed analysis report will be generated which can then be printed.on.

EuroOsmo 7400 The EuroOsmo® 7400 software is a user-friendly software for system control and data acquisition of the KNAUER Semi-Micro Osmometer K-7400. Choose between operating modes: freezing point depression and osmomality determination. All calibrating- and measuring data will be saved with the original measuring curve for archiving purposes. A comfortable search function allows for quick retrieval of measurements in the database. Besides visualizing the measuring curve, a detailed analysis report can be generated and printed.
