3. There is water on the outer wall of the test tube during heating. When heating the test tube, it is necessary to preheat it first, otherwise the test tube will explode due to uneven heating; when heating, use the outer flame of the alcohol lamp to heat. If the inner flame or flame core is used to heat the test tube, the test tube will be unevenly heated and cause explosion; the outer wall of the test tube If there is water, the test tube will be heated unevenly, causing the test tube to burst. There is no preheating; there is water on the outer wall of the test tube; the mouth of the test tube is not tilted slightly downward, causing condensation water to flow back; the bottom of the test tube is in contact with the wick; rinse with cold water immediately after heating, etc.
About the reasons for the rupture of test tubes, this ends the introduction of all the reasons for the rupture of chemical test tubes. I hope it will be helpful to everyone.
