OsmoTech Pro Advanced Instruments Multi-Sample Osmometer

An osmometer is used to determine the concentration of osmotically active particles in a solution, typically expressed in milliosmoles per kilogram (mOsm/kg).

2. Working principle

The OsmoTECH PRO uses the freezing-point depression method.

The measurement process works as follows:

1. Sample loading: A small volume of the sample (approximately 30 µL) is placed in a disposable sample tube.

2. Cooling: The instrument cools the sample below its freezing point.

3. Freezing initiation: The instrument induces crystallization of the sample.

4. Temperature measurement: It measures the freezing temperature as the sample undergoes a phase change.

5. Osmolality calculation: The freezing-point depression is used to determine the sample’s osmolality.

6. Result recording: The measured value is displayed and can be stored or exported.

The underlying principle is that dissolved particles lower the freezing point of a solution. The greater the concentration of osmotically active particles, the greater the freezing-point depression, under appropriate measurement conditions.

3. Main applications

Upstream bioprocessing

Monitoring osmolality in cell culture media and bioreactor processes to help maintain suitable conditions for cell growth and productivity.

Downstream processing

Monitoring osmolality during purification and chromatography to support process consistency.

Formulation development

Evaluating osmolality in drug formulations to support product development and stability studies.

Quality control and manufacturing

Measuring osmolality as part of in-process monitoring and product quality testing.
