Use in Biology In both biology and chemistry, the main primary function of the Erlenmeyer Flask is to mix liquids. Although a scale of measurement is printed in the side of a flask, they are rarely used for measuring purposes due to their uneven sides.

When should a Erlenmeyer flask be used?
Erlenmeyers are used for a variety of purposes. They are used as distillation receiving containers, to hold different layers in an extraction, as reaction flasks, to heat solvent for crystallizations, as the crystallization flask, etc.
Why is an Erlenmeyer flask used for titrations?
In chemistry The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask.
What are characteristics of an Erlenmeyer flask?
Erlenmeyer flasks are recognizable from their basic characteristics: flat bottom, conical body, and long, cylindrical neck. They are named for German chemist Emil Erlenmeyer.
Can you boil in an Erlenmeyer flask?
One of our favorite things about the Erlenmeyer flasks is that you can boil your starters directly in them!
How do you use an Erlenmeyer flask in science?
Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes. Their slanted sides and narrow necks allow the contents to be mixed by swirling without the risk of spills, which is useful for titrations and for boiling liquids.
What equipment do you need for titration?
Acid-base titrations are used to determine the concentration of a sample of acid or base and are carried out using a piece of equipment called a burette. It is a long, glass tube with a tap at the end which can be used to very carefully add drops of liquid to a test solution.
How do you say Erlenmeyer?

Is Erlenmeyer flask heat resistant?
The handle on this Erlynmyer flask offers ease and safety in the laboratory and classroom. These borosilicate glass flasks are heat-resistant and microwave-safe.
Can you put an Erlenmeyer flask on the stove?
If you have an electric stove that has coils embedded under a glass cook top, you are good to go. I have been using some flasks this way for years not worries. I do let it cool a little bit off the burner before dumping it ice cold water. Even the best labware tends to weaken with such an extreme swing in temp.
Are Erlenmeyer flasks accurate?
Erlenmeyer flasks and beakers are used for mixing, transporting, reacting, and filtration but not for accurate measurements. The volumes stamped on the sides are approximate and accurate to within about 5%.
What is a volumetric flask used for in chemistry?
A volumetric flask is lab glass or plasticware used to prepare a solution. It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
Why is a burette used in titration?
Answer and Explanation: The reason why it is preferred to use burette in titration because it can be used to dispense accurate volumes of liquid and it can contain enough amount of reagents for titration. It has graduation marks used to read the volume delivered and it reads from top to bottom starting zero.
What laboratory glassware is used in a titration?
The two most common pieces of glassware used during titrations are burettes (burets) and Erlenmeyer flasks, although sometimes beakers or other flasks are used. The shape of an Erlenmeyer flask helps facilitate the usual mixing, swirling motion with little risk of spillage of the solution being titrated.
What equipment is used for volumetric analysis?
The most common apparatus used in volumetric determinations are the pipette,buret, measuring cylinder, volumetric and conical (titration) flask. Reliablemeasurements of volume is often done with the help of a pipet, buret, and a vo-lumetric flask.
How is burette pronounced?

How is pipette pronounced?

How do you pronounce Buchner?

What is a flask used for?
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
Why can’t evaporation be carried out in an Erlenmeyer flask?
Due to the narrow mouth, they can be stoppered and sealed off. This prevents any spillage and decreases the instances of evaporation. However, in microbiology, Erlenmeyer filter flasks can be used for the preparation of cultures. Some specialized flasks may feature vented closures which improve incubatory gas exchange.
Can you heat a beaker?
Direct heating: Beakers and Erlenmeyer flasks can be heated directly on a hot plate. These containers have a flat bottom and heat will be spread evenly throughout the solution when the solution is also stirred. Other containers that do not have a flat surface should be heated indirectly.
Can Volumetric Flasks be heated?
5. The volumetric flask cannot be heated. If the solute releases heat during the dissolution process, the solution should be cooled after the solution is cooled, because the general volumetric flask is calibrated at a temperature of 20 ยฐ C.
Is an Erlenmeyer flask more accurate than a beaker?
The volumetric flask had the lowest percent error (0.3%), so it is the most accurate. The graduated cylinder and beaker were similar in percent error (2.2% and 3.5% respectively). Both were small, so they are fairly accurate. The flask had the highest percent error (17.4%), so it is the least accurate.
Which glassware is considered as the most accurate when measuring liquids?
Volumetric pipets, sometimes called transfer pipets, are the most accurate pipets. They generally deliver the specified volume ยฑ0.1%, an error of a few hundredths of a milliliter.
Which equipment is best to hold and to measure liquids?
Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ยฑ0.02. Research and testing require precise measurements, and many lab vessels are even designed to account for the liquid residue that clings inside a flask.
