What is an Erlenmeyer flask used for in chemistry?

Answer 1

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:

• pH titrations
• the preparation of mixtures which must be mixed without stirring

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.

Answer 2

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

Answer 3

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.

Answer 4

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.

Answer 5

E-spots/erlenmeyer flaske are used for titration of chemicals or Microbial culture growth.

Answer 6

This is a glass or plastic flask frequently used in chemical laboratories.

Answer 7

it is use for inum inum tubig
