HEATING THE SAMPLE
Use of heat to remove air bubbles, although very effective in some cases, should be handled with care
because it can alter the turbidity of the sample. When heating a sample, the volatile components
from the sample can vaporize, the suspended components can dissolve or the sample characteristics
can change.
Therefore, the heating procedure should be used with extreme care.
The best way is to use a warm water bath and immerse the cuvette with sample into the bath. Heat
the sample only until the visible bubbles are removed.
Note: Always cool the heated sample to the original sample temperature before measurement.
The heating procedure can be used in combination with vacuum or ultrasonic waves application for
a more effective air bubble removal.
