Osmolality is an important measure of concentration for diluted solutions, such as all bodily fluids.

The measuring speed permits rapid series measurements. In the pharmaceutical industry and research, the Osmomat is used to test various aqueous solutions saline drips, etc. Plausibility checks of the results must be performed by the doctor with the support of the pertinent literature. The freezing points of pure water and a solution are measured and compared. That means that one mol of a given non-dissociated substance 6.

The following definitions are used in calculating osmolality: Once the sample solution has reached a specific temperature below the freezing point, crystallization is automatically initiated. The OSMOMAT initiates crystallization by injecting the sample with a stainless steel needle that is cooled by a secondary upper cooling system and at the tip of which small ice crystals have formed through moisture in the air.

Gonotec Osmomat Cryoscopic Osmometer

When crystallization begins, ice forms spontaneously. The heat that was removed during undercooling is released osmokat, the temperature rises spontaneously and the temperature of the sample rises to the freezing point. If the sample consists of water solventequilibrium is achieved as long as the sample contains water and ice. The temperature remains constant because further heat removal does not result in a lowering of the temperature but the formation of ice.

The time of temperature equilibrium is known as plateau time. Only after complete crystallization the temperature does fall again. If the sample consists of a solution, the pure water in the solution crystallizes spontaneously and the substances move to the rest of the solution.

This means that at the time the freezing point temperature is measured, the concentration is higher than in the original solution. A plateau occurs here as well, but it is inclined. Yonotec osmolality reading is taken at the resulting reversal point Figure 1: Freezing point depression of solvent. The temperature is gonltec with a resolution of 1.

If any damage is found, notify the manufacturer: The packaging is re-usable. Please save the packaging in case it becomes necessary to ship the unit back to us for repairs or servicing. This will save you the time and money needed to find equally suitable packaging. We cannot accept responsibility for any missing items reported at a later date.

Do not block the air intake openings on the bottom of the unit. If the power cord plug does not match the conventional power outlets in your location, you may substitute another power cord. It is also important to ensure that the voltage indicated on the nameplate matches that of your electricity network.

Incorrect voltage will cause the fuse in the power supply unit to blow. Five horizontal dashes appear on the digital display. The waiting oamomat of approximately two minutes is necessary for the formation of ice crystals at the upper cooling system. The waiting period can be interrupted by pressing any key. You will feel a slight resistance and hear a click.

The highly sensitive thermistor probe is now immersed in the sample solution. Measuring vessels that are placed loosely or incorrectly will yield non-reproducible results. Now press the measuring vessel holder down into the measuring position noticeable resistance. The measuring vessel is immediately cooled by the lower cooling system.

The current temperature of the solution is shown on the digital display in degrees Celsius. The cooling process can be directly observed.

The moment the undercooling temperature is reached, crystallization is initiated automatically by the injection of ice crystals, and an acoustic signal sounds. The resulting ice formation causes the osmmat to rise to the freezing point of the solution.

Setup and Initial Operation 13 3 Setup and Initial Operation After the measurement process is finished—regardless osmoamt whether it was successful or produced an error message—and the elevator has been raised, the measurement system automatically switches to standby and is ready for the next measurement.

It should therefore be handled according to the safety provisions and precautions for electric measurement, control and laboratory equipment. The unit must be adequately disinfected prior to decommissioning. Equipment must be decommissioned in accordance with local accident prevention guidelines. The unit emits no harmful substances either in operation or while switched off.

Symbols ismomat the unit and its nameplate correspond to the requirements of the following standards: Such hazards and risks cannot entirely be excluded for technical equipment, however. These operating instructions help you gain a basic understanding of the design, the measurement principle, maintenance and servicing of the unit.

Please pay special attention to chapter 7. There must be no visible air bubbles in the liquid! Next, place the measuring vessel securely onto the measuring vessel holder. It should engage slightly. Make sure the lid of the measuring vessel is pointing forward.

The thermistor probe is now immersed in the water. Press the ZERO key. The display shows 0. The measuring vessel holder is lowered and the cooling process begins. The display shows the current temperature. After undercooling has occurred, the needle will automatically be submerged, initiating crystallization.

The freezing point of distilled water will be achieved and recorded by the unit. When calibrating, be aware that the thermistor probe may still be contaminated with sample residues from previous measurements. Following the zero point calibration, a control measurement with water should confirm the exact calibration. If necessary, a new calibration must be carried out. Always use a new measuring vessel with fresh distilled water for each new measurement.

The thermistor probe is now immersed in the liquid. Press the CAL key. The digital display shows the value and the CAL control lamp illuminates yellow. Pressing this key again toggles through the following values:
