Beakers are commonly used in laboratories, hospitals and school science labs. The beaker is named as such because of the small “beak” on the rim, that makes pouring liquids easier. Plastic or glass beakers are cylindrical in shape, have flat bottoms and are used for mixing, stirring or heating chemicals. Science beakers have marking on the side to measure the volume of liquid inside. Choose from a variety of sizes and styles, plus find bottles and jars, and other laboratory supplies such as vials and laboratory funnels, all at great prices.
