What is beaker in laboratory apparatus?

What is beaker in laboratory apparatus? 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? 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.

What is the function of Beaker? Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat. Burets are for addition of a precise volume of liquid.

Why is it called a beaker? Tell-tale signs of the beaker, of course, are the cylindrical glass, usually made of borosilicate, the flat bottom, the lip or beaded rim and the small spout, in the form of a beak.
But interestingly enough, the beaker was likely named after the Beaker people who were master pottery makers during the Neolithic period.

What is a beaker used to measure?

Beakers. These containers, practically synonymous with ‘science’ itself, are used to contain and measure liquids. They are cylindrical with a flat bottom and can range to contain from 10mL to over 1L of liquid.

Why you should not use beaker as a measuring apparatus?

Beakers. For example, a 100 mL beaker might only have marks for every 20 mL, so it would be tricky to gauge the exact volume of a liquid sample falling between the 60 mL and 80 mL marks. If the test you’re performing requires precision, a beaker is not the tool you should use.
