What does a flask measure?
A flask is a type of container made of glass. They are a common piece of apparatus used in laboratories. Their size are chosen by the volume they can hold, and is measured in metric units, like litres (L) or mililitres (mL).
What are science flasks called?
Flasks are useful types of chemistry glassware for containing liquid and performing mixing, heating, cooling, precipitation, condensation, and other processes. These flasks –also known as a science flask, chemistry flask, or a laboratory flask (lab flask )– come in a range of sizes, materials, and uses.
What is a Erlenmeyer flask used for in science?
Erlenmeyer Flask Used to hold and mix chemicals. The small neck is to facilitate mixing without spilling.
What’s the difference between beaker and 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 do we use a volumetric flask?
Use volumetric flasks for precise measurement A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
What is the round flask called?
This object is a boiling flask made from Fry glass. The boiling flask, also known as a round bottom flask, is a chemical vessel with a spherical body and a cylindrical neck. It is most often used when heating solutions, particularly for distillation.
What does flask mean in science?
Laboratory flasks are vessels or containers that fall into the category of laboratory equipment known as glassware. In laboratory and other scientific settings, they are usually referred to simply as flasks.
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 alcohol flasks used for?
Today, in a world in which every imaginable specialized beverage container is available, the flask is used primarily to carry one’s private supply of hard alcohol. It’s commonly given as a groomsman’s gift.
What are characteristics of an Erlenmeyer flask?
Erlenmeyer flasks are recognizable from their basic characteristics: flat bottom, conical body, and long, cylindrical neck. They are named for German chemist Emil Erlenmeyer.
What does Erlenmeyer flask mean?
Medical Definition of Erlenmeyer flask: a flat-bottomed conical flask whose shape allows the contents to be swirled without danger of spilling. Comments on Erlenmeyer flask.
What is the use of a conical flask in science?
Conical flasks are widely used in chemistry laboratories for holding liquids and mixing them by swirling.
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.
Why is an Erlenmeyer flask not accurate?
Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor. They can hold a much larger volume than any of the other types of glassware, however, which makes them useful for mixing solutions.
Round – bottom flasks are used in distillation by chemists as distilling flasks and receiving flasks for the distillate (see distillation diagram). This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
