The advantages of a VPO include the measurement of osmolality in the upper measuring range and a small sample volume (2 to 60 µL, where the Vapro's standard sample size is 10 µL). The measurement time is approximately 120 s/sample.
- Ideal for: research and industrial applications, especially when measuring the osmolality of tissue samples or highly viscous solutions. Additionally beneficial for certain clinical applications that require very small sample volumes or involve highly viscous samples.
- Can test gross samples (e.g., tissues) in addition to solutions.
- Does not alter the physical state of the sample as does freezing point osmometry.
These are the most commonly recommended applications, though its use is not restricted to these areas.
Considerations:
- It should not be used for solutions containing volatile chemicals, as this can produce artificially low or inaccurate results.
- Environmental conditions, such as humidity and pressure, can affect the readings. The device typically requires a controlled environment for optimal performance.
- The thermocouple can be easily contaminated, leading to inaccurate readings. The chemical compatibility of the sensor (thermocouple) must be considered.
