Physical Description
An Erlenmeyer Flask (named after Emil Erlennmeyer) is a common piece of laboratory glassware since 1861. It is also known as as a conical flask or E-flask. It has a conical body, flat base and a narrow cylindrical neck. The flask is usually marked to indicate the approximate volume of their contents.
The flask is chosen to replace a beaker if there is a need to stopper the contents. The narrow neck is sized to accept standard rubber stoppers or corks.
The conical shape and narrow neck facilitates stirring by swirling.
The small neck reduces evaporative losses. The neck may be fitted with side tubes to allow the extraction of produced gases
The flat bottom improves stability on lab benches. A Florence flask has a similar overall use but is more unstable because the body is round and the base is smaller.
Uses
Erlenmeyer flasks are used for:
Disadvantages:
The Erlenmeyer is often stirred with a glass rod even though swirling is more often suggested. Inexperience students often do this while holding the flask at near eye level. A tap with the rod will knock the bottom off dumping the (usually nasty poisonous, hot and corrosive) contents all over the students legs.
Erlenmeyer flasks are used to measure, mix, and store liquids.
Examples:
- container for volumetric analysis
- to collect a solution from filtration
- to contain a liquid
- to make chemical experiments in solution
- to dissolve a substance
I can honestly say I've never heard of an "Erlenmeyer flask stand". 100% of the time I've ever seen an Erlenmeyer flask on a "stand" it was on a ring stand, which is used for ... among other things ... supporting an Erlenmeyer flask. It's also often attached to the stand by a clamp of some sort for additional stability.
This is a conical flask from glass or plastic, frequently used in all chemical laboratories; the Erlenmeyer flask may contain reagents, collect filtrates, labware for a chemical reaction, it is used for titration, etc.
E-spots/erlenmeyer flaske are used for titration of chemicals or Microbial culture growth.

Milliliters, sometimes liters
Yes.
erlenmeyer flask
they are the same
An Erlenmeyer Flask is commonly used for chemistry experiements.
Are you sure you don't mean an Erlenmeyer? That is a special formed flask mostly used in Chemistry
Emil Erlenmeyer created Erlenmeyer flask in 1861.
A flask is basically same as a bottle In chemistry sometime it could mean a thin glas bottle in some different shapes i.e. E-flask (Erlenmeyer flask) with a flat bottom Peter the Viking
The Erlenmeyer flask is named after the German chemist, Emil Erlenmeyer, who developed the instrument in 1861.
A graduated Erlenmeyer flask can measure a volume.
Milliliters, sometimes liters
The Erlenmeyer flask was designed by the German chemist Richard August Carl Emil Erlenmeyer (28 June 1825 - 22 January 1909).
The Erlenmeyer flask is not good for heating solids.
