A plastic dropper is a simple yet essential tool used for transferring and dispensing small, precise volumes of liquid. It typically consists of three parts: a hollow plastic pipette (the tube), a squeezable bulb (usually made of flexible polyethylene or rubber) attached at one end, and a narrow tip with a small opening.

To operate, squeezing the bulb expels air, and releasing it creates suction to draw liquid up into the tube. A second squeeze then dispenses the liquid drop by drop. This mechanism allows for excellent control over dosage.

Commonly made from polymers like polyethylene or polypropylene, plastic droppers are valued for being lightweight, unbreakable, cost-effective, and chemically inert with many substances. They are ubiquitous in medical, laboratory, pharmaceutical, and household settings. Key applications include administering liquid medicines (especially for children and infants), dispensing essential oils, adding reagents in simple tests, crafting, and various DIY projects.

While convenient and disposable, their use with certain corrosive or organic solvents may be limited compared to glass droppers. Nevertheless, their versatility, safety, and precision make them an indispensable item in daily life and basic scientific work.
