The perfect laboratory companions to determine the os molality of aqueous solutions
APPLICATION Freezing point osmometers are used in numerous areas of application, such as medical, pharmaceutical, biotechnology, food and beverage, and chemical industries. In the human body osmotic processes and osmoregulation play an important role: a disturbance of the osmotic equilibrium can lead to numerous health impairments. In many cases, osmometers are used in the medical and pharmaceutical industries to determine the osmolality of blood or urine samples or pharmaceutical formulations by freezing point osmometry. The Gonotec® OSMOMAT® 3000 series have been specially designed for routine measurements in the medical and pharmaceutical fields but due to their robustness, precision and ease of use the devices are the perfect choice for many others areas as well. The OSMOMAT® 3000 determines the total osmolality of aqueous solutions, requires extremely small sample amounts, and allows serial measurements in the shortest possible time.
MEASUREMENT TECHNOLOGY Osmometry is an analytical measuring method for determining the osmotic value / pressure (often referred to as simply the osmolality) of a sample. The osmolality is defined as the concentration of all dissolved – and thus osmotically effective – particles in a solution based on 1 kilogram of solvent. The unit of osmolality is Osm/kg or Osmol/kg. The freezing point of a sample changes depending on the concentration of dissolved substances. Pure water has a freezing point of 0 °C. The solution of one or several substances in water leads to lowering of the freezing point. A solution with an osmotic value of 1 Osmol/kg has a freezing point of -1.858 °C. Through the linear correlation between the freezing point of a sample and its osmolality, freezing point osmometry provides high-precision analytics.
