Samples should be tested more than once and the average value taken.
•
Only distilled water should be used.
•
The water should be at a stable temperature.

The sample must be degreased.

The sample should not be porous. If it is porous then special preparation might be
necessary.

Be certain the sample is completely covered by about 10mm of the liquid.
•
Be certain any air bubbles are removed.

Be very careful not to transfer water to the top pan when using tweezers.
• Samples should be 5 grams or greater.
• Degrease the glass float before using.

on the glass float. It may be necessary to use an anti-static cleaner on the float.

Wash the beaker before filling it with any liquid.
