Product Category

Gonotec Osmomat 010

The Osmomat 010 is a universal cryoscopic osmometer for the determination of molar masses in benzene solution and of the total osmolality in aqueous solutions.
It is based on the well accepted measuring system of the Osmomat 030, which has been used for many years.
The Osmomat 010 is suitable for measuring freezing points of solvents of aqueous and organic solutions which have a freezing point between +10 and -5°C.
The instrument is especially useful for rapid quality control measurements in industrial facilities as well as for research in scientific laboratories.

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 O °C, a solution with saline concentration of 1 Osmol/kg has a freezing point of -1.858 °C
