What is a beaker used for?
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 are beakers in science?
In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. Beakers are commonly made of glass (today usually borosilicate glass), but can also be in metal (such as stainless steel or aluminum) or certain plastics (notably polythene, polypropylene, PTFE).
How do you use a beaker?
Pour liquid into the beaker; pour slowly to avoid splashing the liquid. Use the measuring lines on the beaker to approximate the volume of liquid in the beaker. Stir the liquid inside the beaker with a spoon or stirrer.
What do you mean by 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 science cups called?
Beakers are simple cylindrical shaped containers used to hold reagents or samples. Flasks are narrow-necked glass containers, typically conical or spherical, used in a laboratory to hold reagents or samples. Examples flasks include the Erlenmeyer flask, Florence flask, and Schlenk flask.
What is a skinny beaker called?
Graduated cylinder – A tall skinny cylinder used to measure volumes. It is generally a more accurate way to measure volume than a typical beaker or flask.
What are the small beakers called?
Erlenmeyer flasks come in multiple sizes. As with beakers, these flasks might or might not have volume marked.
Who invented beakers?
Richard Conderbnerellos is credited with the invention of the beaker, but in reality the beaker was invented by Beaker in 1846.
What are the lines on a beaker called?
What is a meniscus? A meniscus is what happens when you put a liquid into a container. When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules.
What is a triangular beaker called?
An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860.
What is the meaning of test tube?
: a plain or lipped tube usually of thin glass closed at one end and used especially in chemistry and biology.
What is a beaker used to measure?
They are also sometimes used to measure the volume of a solid indirectly by measuring the displacement of a liquid. The Beaker’s main function is stirring, mixing and heating liquids. A Beaker has a cylindrical shape with a flat bottom and most include a small spout for pouring.
What is the meaning of weaker?
1. Lacking physical strength, energy, or vigor; feeble. 2. Likely to fail under pressure, stress, or strain; lacking resistance: a weak link in a chain.
