What is an Erlenmeyer flask and how is it used?
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.
What is a conical flask used for?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
What is a erlenmyer flask and how is it used?
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…
What is the use and definition of an Erlenmeyer flask?
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…
What is an erlenmyer flask?
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…
Why is an Erlenmeyer flask better to use than a volumetric flask?
I my experience the Erlenmeyer flask is better for certain things than others.... what I mean is that is has labeled measurements on the side and the increments are based on the size of the flask but the volumetric flask is better is you want to dilute a solution at a certain volume to find....molarity they both have good qualities it just depends on what you want to use it for.
Use of erlenmeyer flask?
Erlenmeyer flasks are used to measure, mix, and store liquids. Erlenmeyer flasks are often used to heat liquids, e.g. 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 to prevent the flames from directly touching the glass. An alternative way to set up…
What are the uses of an Erlenmeyer flask?
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…
What is the difference between beaker and an Erlenmeyer flask?
An Erlenmeyer flask is a widely used type of laboratory container which features a conical base with a cylindrical neck. The conical flask is similar to the beaker, but is distinguished by its narrow neck. The neck allows the flask to be stoppered using rubber bungs or cotton wool. The conical shape allows the contents to be swirled or stirred during an experiment. The narrow neck keep contents from spilling. The smaller neck also slows…
What is the use of a erlenmeyer flask?
Erlenmeyers are used in chemistry labs for titration, e.g. for pH, as they can be held and the contents mixed single-handed leaving the other hand free to add reagent. Erlenmeyer flasks are suitable for heating liquids, e.g. with a Bunsen burner. 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…
