What is a flask in a lab?
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. Laboratory flasks have traditionally been made of glass, but can also be made of plastic.
What are lab flasks called?
Share: 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 the correct description of a flask used in a lab?
Laboratory flasks are lab vessels with wide bodies and narrow, tubular necks. They can be used for mixing, measuring, and heating chemicals, samples, and solutions. A type of labware, laboratory flasks are made of glass or plastic and specified by volume. Often, a stopper or cap is used to seal the opening at the neck.
What is flask in microbiology?
Erlenmeyer flasks are also used in microbiology for the preparation of microbial cultures. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking. This phenomenon has been intensively characterized for shake flask bioreactors.
What is a volumetric flask used for?
The Volumetric Flask A volumetric flask is used when it is necessary to know both precisely and accurately the volume of the solution that is being prepared. Like volumetric pipets, volumetric flasks come in different sizes, depending on the volume of the solution being prepared.
What is a flask shape?
: resembling a typical flask in shape usually : necked and either globular or flattened in body.
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 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.
What is the function of volumetric flask?

What is the mark on a volumetric flask called?
The neck of volumetric flasks is elongated and narrow with an etched ring graduation marking. The marking indicates the volume of liquid contained when filled up to that point. The marking is typically calibrated “to contain” (marked “TC” or “IN”) at 20 °C and indicated correspondingly on a label.
