A beaker is a cylindrical glass or plastic vessel used for holding liquids. It is a multi- purpose piece of equipment used for containing a chemical reaction, measuring liquids, heating them over a Bunsen burner’s flame or collecting them in a titration experiment.

What is a beaker easy definition?
Definition of beaker 1 : a large drinking cup that has a wide mouth and is sometimes supported on a standard. 2 : a deep widemouthed thin-walled vessel usually with a lip for pouring that is used especially in science laboratories.
What are beakers called?
Beaker Categories The standard beakers known as Griffin beakers are lower beakers, and their height is about 40% of its diameter. The taller beaker is known as Berzelius beakers. They are thin, and their height is double their diameter. The third type of beaker is called a crystallizer.
Why is it called a beaker?
The word comes from the Greek root bikos, “earthenware jug.”

What is a beaker made of?
Glass: Glass beakers are typically made with borosilicate glass which has boron trioxide which allows it to resist extreme temperature changes. It has excellent chemical resistance and can withstand temperatures up to 400°C.

What are glass beakers?
A beaker sometimes called a Griffin beaker is a borosilicate glass container for stirring, mixing and heating liquids and is usually used in laboratories. These glass beakers have a flat bottom and spout /beak to assist pouring the liquid out.
What are the different types of beaker?
- Beakers.
- Boiling Flasks.
- Cell Culture Flasks.
- Dewar Flasks.
- Erlenmeyer Flasks.
- Filter Flasks.
- Kjeldahl Flasks.
- Other Flasks.
Who discovered beaker?
The Griffin beaker’s name refers to John Joseph Griffin (1802–1877), an English chemistry enthusiast. His interest in bringing chemistry to the common man led him to publish popular works on the subject and eventually to begin supplying scientific apparatus, including his eponymous beakers.
Is a beaker a cup?
A beaker is a beverage container, typically of non-disposable plastic, or a ceramic cup or mug without a handle, much like a laboratory beaker.
What does beaker look like?
Beaker has bulging eyes, a shock of red hair, and a drawbridge mouth which serves as a frown. He was originally puppeteered and voiced by Richard Hunt until Hunt’s death in 1992, when the role was taken over primarily by Steve Whitmire.
What are beakers used to measure?
Measuring Beaker are tools used to measure the volume of liquids. Beakers are also used for stirring, mixing and heating liquids found in laboratory settings. Beakers are graduated. The liquid can be poured directly into the beaker and measured with the help of markings on the beaker.

What do you put in a beaker?
Lab Equipment Used for Liquids A beaker is a cylindrical container used to store, mix and heat liquids in laboratories. Most are made of glass, but other non-corrosive materials, such as metal and heat-resistant plastic, are also used. Beakers usually have a flat bottoms and a lip around the top.
Why are beakers shaped like that?
Beakers have a cylindrical shape, with flat bottoms so that that they can be set onto many different types of surfaces, and they usually have a thick top with a spout to make it easier to pour liquids.

What are chemistry bottles called?
Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid.
What is a chemical container called?
Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.
What glassware is used in chemistry?
Beakers – One of the most common types of laboratory glassware, beakers are basic containers used to hold samples and reagents. Burettes – Used to dispense liquid in exact quantities. Pipettes (Bulb and Graduated) – Used to move a small, measured amount of fluid.
