What is beaker and its uses?

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. They can be used to contain a small chemical reaction.

What is beaker in laboratory?

The beaker is one of the most common pieces of glassware in the laboratory. It is a simple cylindrical container used to hold solids and liquids with sizes ranging from very small (10 mL) to very large (4,000 mL). It has a lip for ease of pouring and decanting liquids.

What is a 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.

Who invented beaker?

Richard Conderbnerellos is credited with the invention of the beaker, but in reality the beaker was invented by Beaker in 1846.

What is the function of burette?

A burette is used to dispense small volumes of liquid called aliquots, or sometimes gas, with high accuracy. It consists of a long glass tube with a valve at one end to control the flow of liquid. Burettes serve essentially the same purpose as a pipette.

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.

How precise is a burette?

10 mL burettes are usually graduated each 0.05 mL, while 25 mL and 50 mL burettes are usually graduated each 0.1 mL. 0.050 mL out of 50 mL is 0.1%, and that’s about maximum precision that we can get from volume measurement when using burette.

What do you use a beaker for in chemistry?

A beaker is a key piece of chemistry glassware. Science Photo Library / Getty Images. 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’s the difference between a flask and a beaker?

Related items. Laboratory flask. In laboratory equipment, a beaker is generally a cylindrical container 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 milliliter up to several liters. A beaker is distinguished from a flask by having …

What are the different types of Bell Beakers?

The two main international bell beaker styles are: the All Over Ornamented (AOO), patterned all over with impressions, of which a subset is the All Over Corded (AOC), patterned with cord-impressions, and the Maritime type, decorated with bands filled with impressions made with a comb or cord.

Can a beaker be used with a flat scale?

These beakers usually do not have a flat scale. The presence of a spout means that the beaker cannot have a lid. However, when in use, beakers may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout.
