Erlenmeyer flask is a sort of lab apparatus called after Emil Erlenmeyer, a German chemist who formulated it in the 19th century. It is used extensively in chemistry and biology labs for different reasons, such as mixing, storing, and heating liquids.
Erlenmeyer flasks are cone-shaped glass containers with a slender neck and wide bottom; the body form is like that of a cone.
Erlenmeyer flasks are usually used to mix or heat liquids by stirring in them or by their use in shake-flasking processes. The narrow neck helps to prevent any spatters.
The flask’s cone shape facilitates dispensing and the tube-shape of its neck allows stoppers or aluminum foils to be used as covers.
Their conical shapes make Erlenmeyer flasks perfect for heating liquids using a laboratory burner due to good heat distribution.
The conical shape of these enables efficient stirring hence they can be used with magnetic stirrers.
A cylindrical glassware with a flat bottom and a pour spout is called a beaker; often times they have lips to simplify pouring.
In general, these versatile containers can function as storage units, mixers, heaters, etc., for liquid substances in most cases, simple reactions such as holding chemicals during experiments.
Liquid can easily be poured out from a beaker because of the presence of lip and spout at the rim; however it is not designed for precise measurements.
Gentle heating is possible using beakers but it is not ideal for strong or prolonged heat unlike Erlenmeyer flasks.
On the other hand beakers, unlike Erlenmeyer flasks, are not as good for stirring intensely or for rapid stirring during certain processes.
Beakers often have volume marks that are approximately correct on their sides while these are usually not as precise as those on a graduated cylinder.
To conclude, in view of tasks involving swirls and splashes in reactions, Erlenmeyer flasks are best suited when doing processes like titrations and measuring. Beakers on the other hand can serve multiple purposes in a laboratory. The decision which to use will depend on what is required for a specific experiment or procedure being performed at a given time.
