What are beakers used for?
Beaker – A beaker is a glass container with a flat bottom and a small spout for pouring. It is used in the chemistry lab for mixing, heating, and stirring liquids. Beakers come in various sizes and are shaped like a cylinder.
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).
What are beakers and flasks used for?
Erlenmeyer flasks and beakers are used for mixing, transporting, reacting, and filtration but not for accurate measurements. The volumes stamped on the sides are approximate and accurate to within about 5%. Beakers are used to contain volumes of liquids.
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.
Why are beakers called beakers?
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.
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 small beakers called?
Erlenmeyer flasks come in multiple sizes. As with beakers, these flasks might or might not have volume marked.
What are science tubes called?
burette. a glass tube marked with a scale and with a tap at the bottom. It is used in laboratories for allowing a small measured amount of a liquid to flow into something.
What does burette mean?
Burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
What does a flask look like?
Round-bottom flasks are shaped like a tube emerging from the top of a sphere. The flasks are often long neck; sometimes they have the incision on the neck, which precisely defines the volume of flask. It is a flask with an approximately pear- shaped body and a long neck with a circumferential fill line.
Whats the difference between a beaker and a flask?
Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.
Why use an Erlenmeyer flask instead of a beaker?
The Erlenmeyer flask offers a slight advantage in accuracy due to its tapered sides. The size of the beaker or flask should be chosen to allow for more liquid to be added during the titration process. This makes it simpler than subtracting once the titration is complete. There is a valve at the bottom of the burette.
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.
