Thoroughly clean and dry outer surface of the tube by means of a paper napkin, and individually weighed each tube individually. Quantitatively, the content of each tube is removed. For this purpose the tube is opened, washed with an inner surface, using first water, then isopropyl alcohol. During the test, keep all parts of the tubes, including caps and crimping tools. Dried and reweighed tube complete with separated parts. The difference between the two weight parameters registered the weight of the contents of the tube.
