Freezing point osmometry The KNAUER freezing point osmometer The K-7400S Semi-Micro Osmometer can determine the exact freezing point of aqueous solutions. The osmolality of various samples like pharmaceutical solutions or soft drinks can thus be easily determined. Freezing point osmometry The measurement principle of the K-7400S Semi-Micro Osmometer is based on the colligative property of freezing point depression. If a solute is added to a liquid this results in a decreased freezing point of the solution. The depression is 1.858 K per 1 mole of ideally solved compound in one liter of water....

Freezing point osmometry RS-232 interface Connection for printer or software control. Parking position The four pedestals ensure safe storage of the measuring head while the device is not in use. o Technical data Sample volume 50 - 150 pl Measuring head With the stirring wire and its high-precision thermistor the measuring head is a key component of the osmometer. Osmolality range 0 - 2000 mOsmol/kg Test time ~ 2 min Precision SD < 4 mOsmol/kg [0 - 400 mOsmol/kg], Linearity ± 1.5 % [0 - 2000 mOsmol/kg] o Control via keypad The instrument can be fully controlled via the keypad....

Freezing point osmometry 1100 1000 isotonic range = 300 mOsmol/kg ± 10% For process monitoring and quality checks of reagents and chemicals. non-isotonic drinks were analysed using the K-7400S Semi-Micro Osmometer. All beverages advertised to be isotonic, had osmolality values within the range of 300 mOsmol/kg ± 10% (grey bar). Thus, they met the specifications for isotonic drinks defined by the European Food Safety Authority. In contrast, a usual softdrink or an alcoholic beer exhibited much higher osmolalities. Plasma osmolality = 290 ± 10 mOsmol/kg Especially infusion solutions but also solutions...

Freezing point osmometry Ordering information KNAUER is one of the pioneers in the field of osmometry K-7400S Semi-Micro Osmometer with Measuring head, incl. calibrating solutions (400, 850 mOsmol/kg) and plastic sample tubes Accessories & spare parts In many laboratories, the accurate concentration of solved molecules in a liquid is essential for daily work routine. The KNAUER K-7400S Semi-Micro Osmometer is ideally suited for this task, since most solutes in a liquid can be measured. The determination of total particle concentration or osmolality becomes fast and simple. KNAUER is one of the...
