HEATING THE SAMPLE
This procedure can be very effective however it 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.
The heating procedure should be used with extreme care.
Use a warm water bath and immerse the cuvette filled with sample into the bath. Heat the sample
only until the visible bubbles are removed.
Note
: Always cool the heated sample to the original temperature before measurement.
The heating procedure can be used in combination with vacuum or ultrasonic waves application for
a more effective air bubble removal.
