eyedroppers

An eyedropper, also known as a dropper, is a tool used to transfer 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 draws liquid into the tube. Releasing the bulb then dispenses the liquid, allowing for precise measurement and application of small volumes.

Eyedroppers are commonly used in laboratories for handling chemicals and reagents. They are also employed in medicine for administering eye drops or other liquid medications. In art and crafts, eyedroppers can be used for various purposes, such as applying dyes, inks, or paints. Their simplicity and accuracy make them a versatile tool across many disciplines.

The design of an eyedropper allows for easy cleaning and reuse, although sterility is crucial in medical and laboratory applications. Disposable eyedroppers are also available for single-use scenarios to prevent contamination. The volume capacity of eyedroppers can vary, with smaller ones suitable for micro-applications and larger ones for more substantial liquid transfers. The tip of the eyedropper is usually tapered to facilitate controlled dispensing of the liquid.
