Vapro® Vapor Pressure Osmometer

Discovery Diagnostics, Canadian distributor for Wescor's Vapro® Vapor Pressure Osmometer for osmotic measurement of fluids, viscous samples & tissue specimens

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 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.

Why Vapor Pressure? “
Vapor pressure measurement is the fastest and easiest method of determining osmolality, and the thermodynamic limitations of vapor pressure osmometry are least restrictive. For these reasons, vapor pressure osmometry is the method of choice 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 pre- cludes 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.

The fundamental advantages of vapor pressure osmometry are now embodied in the most intelligent osmometer ever produced. Wescor’s Vapro offers an intuitive approach that frees you from intensively “managing” an instrument

Features
Menu Driven
Streamlined user interface for quick access to menu items and common functions. User-Selectable Measurement Modes: Single sample; Auto Repeat Mode for repeat measurements of the same sample; Averaging Mode for precision measurements; Delayed Start Mode for samples requiring longer equilibration times. Four user-selectable languages (English, French, German, Spanish).
Superb Accuracy

Unsurpassed by any other method, error is less than 1% in the clinical range.

Self Cleaning
Self-cleaning thermocouple reduces maintenance and improves performance.

Easy Calibration
A push of a button automatically sets the calibration parameters.

Economical
Low initial cost, no expensive proprietary supplies

Trouble-free Self Diagnostic Operation
Few moving parts, no mechanical adjustments, no mechanical breakdowns.
Automated circular sample slide and chamber locking operation, which places all the controls on the front panel.
Built in clock records and displays a date code for each sample result.
