VAPRO® Vapor Pressure Osmometer Model 5600

The advantages of vapor pressure osmometry are now embodied in the most intelligent osmometer ever produced! The VAPRO Vapor Pressure Osmometer brings unprecedented simplicity, convenience, and accuracy to the routine determination of osmolality to help meet the demands of today’s clinical and research laboratory. Auto-calibration, a self-cleaning thermocouple, self-diagnostics, statistical analysis, and computer interface with printout capabilities make the VAPRO osmometer a must for any busy laboratory. With a small sample requirement you can assay hard-to-get or expensive samples using the vapor pressure method.

Measurement Technique

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 applications.

  • Superb Accuracy: Error rate is less than 1% in the clinical range. 
  • Self-Cleaning: The thermocouple cleans itself  reducing maintenance and improving performance. 
  • Easy Calibration: automatically set the calibration parameters with the push of a button. 
  • Economical: Low initial cost. 
  • Lab Report Software: Combine user-provided information with measurement results directly from the VAPRO to produce a printable and savable report.
