Measurement Technique
The total osmolality of aqueous solutions is determined by comparative measurements of the freezing points of pure water and of solutions. Whereas water has a freezing point of 0°C, a solution with saline concentration of 1 Osmol/kg has a freezing point of -1.858°C.
Advantages
- Ease of use: Controlled with a touch screen display and step by step user-guidance for all measurement functions.
- Calibration: Automatic, two or three point calibration.
- Design: Robust design that makes it easy to handle and maintain.
- Data Tracking: Built in printer for physical copies and USB or RS232 connections for digital copies. Last results remain available after switching to automatic stand-by mode.
- Quality Management: QM assistance for the laboratory supervisors.
