MindMap Gallery Introduction to chemical experimental instruments and test tubes
Test tubes are commonly used instruments in chemical experiments for containing chemical reactants and conducting small-scale experiments. Made of glass or plastic, test tubes come in various sizes to meet the needs of different experiments. They can withstand a certain level of high temperature but should avoid sudden temperature changes during heating to prevent cracking. After use, test tubes need to be thoroughly cleaned using a dedicated brush and detergent to ensure accuracy in subsequent experiments.
