A dropper is a simple device used to dispense small amounts of liquid. It typically consists of a glass or plastic tube with a rubber bulb at one end. When the bulb is squeezed, it creates suction that draws liquid into the tube, and releasing the bulb allows the liquid to be dispensed drop by drop. Droppers are commonly used in laboratories, medicine, and cooking. In medical settings, droppers are often used to administer medications, such as liquid medicine or eye drops. They provide precise control over the amount of liquid dispensed, making them essential for accurate dosing. Additionally, droppers can be found in various sizes to accommodate different applications.
