What is the function of a flask?
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
What is flask in chemistry?
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.
How do you use a science flask?
How to use a volumetric flask
- Add your solute to your solution.
- Add enough solvent to dissolve the solute.
- Keep adding your solvent until it gets close to the line marked on the volumetric flask.
- Use a pipette to fill the flask.
What is 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.
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 a flask used for alcohol?
Simply called as flasks, these are small containers for holding hard liquor and carrying it around in your pocket conveniently. Over time, these hip flasks have evolved from a rudimentary animal bladder in the Stone Age to what we see today, a stainless steel vessel or a pocket flask.
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 is a flask used to measure?
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 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 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.
Can an Erlenmeyer flask be heated?
One of the main uses for Erlenmeyer flasks is for recrystallization, which of course involves heating the container and contents. So, although Erlenmeyer flasks can be heated, they are not specifically designed for high temperature, constant heating applications. For this, you should use a boiling flask.
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.
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.
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.
