Osmometers Semi-Micro 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. Advantages • Simple handling • 2 to 4 point calibration • Short measurement time (2 – 3 min) • Reasonable price • Fully automated measurement • Automatic storage of measurement values • Air cooling • Cooling process is thermistor controlled • Cooling chamber will not freeze

Medical* applications • Poisoning • Monitoring kidney functions • Diabetes Insipidus • Shock (trauma) • Clearance control • Lactation control • Dialysis control • Control of infusion solutions in pharmacies • Control of iso, hyper, and hypotonic solutions • Blood control and control of other transfusion supplies • Control of osmotic pressure in cell culture media for biotechnology and genetic engineering * In vitro diagnostics approval required for EU and other countries is in preparation. Operation 150 μl of an aqueous solution or a biological fluid are super cooled below the melting point....
