Determination of total osmolality of bio­ ­
logical fluids and other aqueous liquids
Typical applications for the Semi-Micro Osmometer K-7400 range from routine testing of
physiological fluids such as blood serum and urine in clinics* up to quality control of food
products like milk or isotonic soft drinks.
Principle
The Semi-Micro Osmometer K-7400 determines the osmolality by measuring the freezing point
depression of the liquid sample. Osmolality describes the concentration of osmotic effective
particles in solutions, independent from type, composition or electrical charge. The osmolality
refers to the mass of the solution, meaning 1 kg of pure water.
