MindMap Gallery Instructions for using chemical experimental instruments such as droppers
When using chemical experimental instruments such as droppers, select appropriate instruments according to experimental needs. When operating, follow correct operation methods, such as controlling the dripping speed by gently pressing the rubber head when using a dropper to draw up and dispense liquid. At the same time, to ensure safety, wear protective glasses and gloves to avoid liquid splashing into the eyes or skin. During the experiment, accurately record data such as instrument specifications and liquid volume. After use, clean the instruments in time to keep them clean and accurate for next use.
