Function of flask

Answer 1

A flask is essentially a bottle. * In a labs, glass flasks (Erlenmeyer, Florence) are used for mixing heating and storing solutions. Sometimes they are graduated to show the volume of material that they contain.

* Vacuum flasks are more robist, ususally with a side arm to remove gases * Insulated flasks keep things cold like liquid nitrogen

Answer 2

A volumetric flask is a container that is used to measure the volume of a liquid with extremely high accuracy. It is the best way to measure a specific quantity of a liquid.

It cannot be used to measure just any volume (unlike a graduate cylinder) -- each volumetric flask is designed to measure one specific volume. Because of that they come in a variety of sizes, such as 1 mL, 5 mL, 10 mL, 25 mL, 50 mL, 100 mL, 250 mL, 500 mL, 1000 mL, 2 L, and 5 L.

A volumetric flask is tear-drop shaped, with a very long neck and a round section at the bottom (and a flat bottom so that it stands upright on a flat surface)

In a volumetric flask, you should also fill the flask until the bottom of the meniscus is at the level of the marked ring around the neck of the flask. Hold the flask at eye level and carefully add liquid (drop by drop if necessary) until the bottom of the meniscus is exactly at the level of the marking on the neck of the flask.

Answer 3

It stores stuff, and you can mix chemicals and make solutions easily without the use of a stirring rod or something like that. It could also be a tool for measuring milliliters.

Answer 5

A filtration flask is a container used to collect the filtrate from the filtering.

Answer 6

If you think to a Florence flask this is used as a container for liquids.
