Volumetric flask leak test method?
A: Before use, check whether the volume bottle stopper is tight， please put tap water into the bottle near the marking line, cover the stopper, hold the stopper by hand, invert the volume bottle, and observe whether there is water in the bottle mouth. If it does not leak, after the bottle is upright, turn the bottle stopper about 180 ° and then invert and try again. In order to keep the plug from being lost, the plastic wire rope is used to smash it on the bottleneck.
