Osmomat 3000 basic Freezing point osmometer
The Gonotec® single sample cryoscopic osmometer has been developed in particular for the operator who rather emphasizes on simple handling and precise measurements than on automatic documentation.
The Osmomat 3000basic is the basic version of the OSMOMAT 3000. It determines the total osmomality in aqueous solutions in very small sample volumes and it is suitable for extreme measuring tasks just like the OSMOMAT 3000.
With this basic version measurements have to be recorded by the operator, as the unit is neither equipped with a printer nor data output.
Advantages
- The OSMOMAT 3000basic can be controlled easily and comfortably via a touch screen display
- Step by step user guidance through all measurement functions
- Comfortable calibration routine
- 2 or 3 point calibration
- The tough design of the measuring equipment makes the OSMOMAT 3000basic easy to handle and to maintain
- Language options: German / English

Measurement: Freezing point osmometer
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.
