What is the use and definition of an Erlenmeyer flask?

Answer 1

The triangular shape of the Erlenmeyer flask aids in the mixing of the liquid inside. When you swirl the flask, the liquid moves up the sides without coming out the top.

They are used in applications where solutions must be mixed multiple times. When doing a titration analysis, small amounts of reactant are added to a solution, usually until an indicator changes color, and the solution must be mixed after every addition.

When making a dilution of a stock solution, the easiest way is to add a measured amount of stock to a measured amount of solvent in an Erlenmeyer and swirl to ensure thorough mixing.

Erlenmeyer flasks are often used to heat liquids with a Bunsen burner. For that purpose, the flask is usually placed on a ring held to a ring stand by means of a ring clamp. A wire gauze mesh or pad is usually placed between the ring and the flask.

Answer 2

An Erlenmeyer flask is a type of laboratory glassware used for heating, mixing, and storing liquids. It has a conical shape with a flat base, which allows for easy swirling of liquids without spilling. The narrow neck of the flask helps prevent splashing and allows for the use of a stopper or tubing.

Answer 3

An Erlenmeyer flask has a round bottom with sides that slope up to a narrow neck. These often are graduated for approximate volume measurements.

Here are some reasons to use an Erlenmeyer flask:

* Erlenmeyer flasks are less likely to spill because of their narrow neck.

* Evaporation is slowed down in the Erlenmeyer flask because of the narrow neck.

* Solutions can be swirled easily unlike in a beaker due to the sloping sides.

* The narrow opening allows it to be stoppered easily.

Answer 4

An Erlenmeyer flask, also known as a conical flask, is a widely used type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.

The Erlenmeyer is usually marked on the side (graduated) to indicate the approximate volume of contents, and has a spot of ground glass or enamel where it can be labeled with a pencil. It has a tapered body and narrow neck. The opening usually has a slight rounded lip so that the Erlenmeyer can be easily stoppered using a piece of cotton wool, rubber bung or similar.

Answer 5

An Erlenmeyer flask is an important laboratory glassware put to multiple uses. This conical flask consists of an inverted conical base with a cylindrical neck. The glassware usually contains some graduation marks to indicate the approximate value of its contents. The flask is named after the famous German chemist Richard Erlenmeyer, who created it in the year 1861.

The conical Erlenmeyer flasks are somewhat similar to a beaker; the main difference being its narrow neck. It is generally used to heat substances, these flasks are also used for titration and for the preparation of Microbial cultures. These flasks are also very important in the process of culturing bacteria.

Advantages of Erlenmeyer Flasks

• The flask can be stoppered using rubber bungs or hydrophobic cotton.
• The contents in the flask can be stirred or swirled without the risk of spilling during an experiment.
• Liquids / solutions can be safely transported · The flask can be used to deal with violent reactions.
• Smaller neck of the flask also reduces the loss due to evaporation · The flask is unlikely to tip over.

Use of Erlenmeyer Flask

• Clinical Laboratories
• Microbiology
• Educational Laboratories

Answer 6

An Erlenmeyer flask is a laboratory flask, commonly associated with chemistry. It's conically shaped with a cylindrical opening. Erlenmeyer flasks are usually used in titration, determining the unknown concentration of a reactant by analyzing the ratio of the volumes when a solution has reached an equivalence point (pH of 7). They are also used for heating liquids, containing microbial cultures, and other measuring, mixing, and pouring tasks involved with laboratory work. The advantage to an Erlenmeyer is it's stability in both material (often borosilicate glass) and shape.

Answer 7

It is defined as "A complicated device in which you empty your body of your internal fluids."

Answer 8

an Erlen Meyer flask is device that can hold liquids and measure

Answer 9

An Erlenmeyer flask has a round bottom with sides that slope up to a narrow neck. It is mainly used when you are mixing substances or using a filter, so it collects the filtrates.

Answer 10

Flat bottom conical flask.
