What is an Erlenmeyer flask and what is it used for?
What are characteristics of an Erlenmeyer flask?
Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck. They may be graduated, and often spots of ground glass or enamel are used where they can be labeled with a pencil. It differs from the beaker in its tapered body and narrow neck.

Why is an Erlenmeyer flask not accurate?
Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor. They can hold a much larger volume than any of the other types of glassware, however, which makes them useful for mixing solutions.
What is the difference between Erlenmeyer flask and conical flask?
No,there is no difference between them. Both are same. Both are used in many chemical experiments in laboratory such as for titration,for boiling,for chemical mixing and so on.
How do you hold a flask if you are mixing chemicals?
How do you hold and move a flask if you are mixing chemicals? You transport them with a forcep. What Should you do if something gets in your eyes during a lab?
What does the Erlenmeyer flask do?
The Erlenmeyer flask was created by Emil Erlenmeyer, a German chemist, in the 1860s. He developed a flask that has a flat bottom with a tapered neck. … These flasks are useful for mixing solutions for chemical reactions, or can be used for drying and vacuuming chemical product to remove water.
Why use an Erlenmeyer flask instead of a beaker?
Swirling in a conical flask makes the solution run back down, rather than slosh over the edge, so there is less chance of spilling. With a beaker it is more likely that some part of your sample will slosh out.
What is the meaning of thermos flask?
n vacuum flask that preserves temperature of hot or cold drinks. Synonyms: thermos, thermos bottle Type of: vacuum bottle, vacuum flask. flask with double walls separated by vacuum; used to maintain substances at high or low temperatures.
What does an Erlenmeyer flask measure?
The Erlenmeyer flask has diverse uses such as holding and measuring chemical liquid samples, but can also be used to mix, heat and boil chemicals.
What does flask mean?
noun. a bottle, usually of glass, having a rounded body and a narrow neck, used especially in laboratory experimentation. a flat metal or glass bottle for carrying in the pocket: a flask of brandy.
What does vacuum flask mean?
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask’s surroundings.
What is the difference between a beaker and a flask?
Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. … The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.
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.
Can you heat Erlenmeyer flask?
So, although Erlenmeyer flasks can be heated, they are not specifically designed for high temperature, constant heating applications. For this, you should use a boiling flask. The conical shape of an erlenmeyer flask creates a sharp angle between the bottom and sides of the flask.
