Osmomat 010 Freezing point osmometer

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.

Advantages

  • automatic calibration by switch
  • no ice formation in the lower cooling system: reliable measurements even for long working periods
  • measuring time approximately 1 min: valuable in case of serial measurements
  • measurements and determination microprocessor controlled
  • minimum sample volume: 50µL
  • disposable plastic measuring vessels save time and costs
  • automatic error detection and display
  • optional measurement documentation by integrated matrix printer: date, time, sample number and measuring result are printed

Measurement: Freezing point osmometer

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.

Applications

Routine measurements in medical applications as well as measurements in industry and research.The Osmomat 010 determines mol masses in benzene solutions and the total osmolality of aqueous solutions. Small sample volumes and short measuring times allow extreme measuring requirements and serial measurements.
