The fundamental advantages of vapor pressure osmometry are now embodied in the most intelligent osmometer ever produced.
START WITH THE BEST! The Vapro Vapor Pressure Osmometer brings unprecedented simplicity, convenience, and accuracy to the routine determination of osmolality to help meet the demands placed on today’s clinical and research laboratory.
Auto-calibration, a self-cleaning thermocouple, self-diagnostics, statistical analysis, and computer interface/printout capabilities make the Vapro, osmometer a must for any busy laboratory. The small sample requirement allows you to assay hard-to-get or expensive samples using the superior characteristics of the vapor pressure method.
Product Description: Vapro®Vapor Pressure Osmometer
The Vapro® Vapor Pressure Osmometer, can be used to determine the osmolality in any type of sample: fluids, viscous, and even tissue, giving the Vapro great versatility in clinical med
icine or biomedical research applications. The Vapro osmometer requires a sample volume of only 10 microliters. Osmolality is displayed in 90 seconds.
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. To record more detailed information, or to capture the results in a computer, Vapro Lab Report software for Windows operating systems combines user-provided information with measurement results directly from the Vapro to produce a printable, savable report.
Why Vapor Pressure?
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.
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.
- Functions are selected from a simple and logical menu.
- Streamlined user interface for quick access to menu items.
- User-Selectable Measurement Modes: Single sample; Auto Repeat Mode; Averaging Mode for precision measurements; Delayed Start Mode for samples requiring longer equilibration times.
- User-selectable languages (English, French, German, Spanish).
Unsurpassed by any other method, error is less than 1% in the clinical range.
Self-cleaning thermocouple reduces maintenance and improves performance.
A push of a button automatically sets the calibration parameters.
Low initial cost, economical proprietary supplies.
