A large drinking cup that has a wide mouth and is sometimes supported on a standard. : a deep widemouthed thin-walled vessel usually with a lip for pouring that is used especially in science laboratories. A beaker is typically a cylindrical container with a flat bottom used in lab equipment. Most also have a tiny spout (or “beak”) to enable pouring, as seen in the image below. Beakers come in a huge variety of sizes, ranging from one millilitre to several litres.
Because its sides are straight as opposed to sloping, a beaker can be distinguished from a flask. The Philips beaker, a beaker with slightly conical sides, is an exception to this rule. In most drinkware, the beaker shape is present. We are also going to discuss what a beaker is used for, what beakers are used for in science, and beakers used in chemistry labs.
Beakers are frequently made of glass but they can also be made of metal (such as stainless steel or aluminium), or some plastics. Beakers used in laboratories are vessels in which liquid is kept so that it can easily be mixed or heated.
The bottom of the beaker is flat in appearance. On the tip, a small depression is made for pouring liquid or solutions. Low-form beakers have a height of about 1.4 times the diameter. It is also known as the Gryphon beaker. These are used for different purposes. Tall form beakers have a height of about twice their diameter. Flat beakers are known as crystallizers.
Beakers can be used to hold liquid or solid samples or as a container for reactions. They are also used to collect filtrates from filtering operations as well as liquids from titrations. It is used for stirring the liquid. It is useful as a reaction container. They are also used to catch liquids.
