A medicine dropper is a small, tube-like device used to dispense liquids in precise amounts. It typically consists of a glass or plastic tube with a rubber bulb at one end. When the bulb is squeezed, it creates a vacuum that draws liquid into the tube, allowing for accurate measurement and delivery of medications or other liquids. Medicine droppers are commonly used in healthcare settings, especially for administering liquid medications to children or pets. They can also be found in laboratories for transferring small volumes of liquids. The ability to control the amount of liquid dispensed makes them essential tools in various applications, including pharmacy and science experiments.
