The freezing point osmometer enables freezing point depression to be measured. The measurement run is completely automated after the sample is injected. The instrument is equipped with a peltier 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. The freezing point osmometer can be controlled by EuroOsmo7400 software. It is possible to work with the osmometer as standalone device or with a special printer or with software.
