Beaker (medical)
A beaker (pronounced: /ˈbiːkər/) is a simple container for stirring, mixing and heating liquids commonly used in many laboratories including those found in medical laboratories. Beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres.
Etymology
The term "beaker" comes from the Middle English word "biker" which was derived from the Old Norse "bikarr" meaning "drinking cup". The term was later adapted to refer to the scientific instrument due to its similar shape and function.
