C1-C2 (Specialist)Technical/Scientific
Definition
Meaning
A conical laboratory flask with a flat bottom and a narrow cylindrical neck, used for mixing, heating, and storing liquids.
In broader scientific contexts, it represents standardized laboratory equipment; metaphorically, it can symbolize scientific experimentation, precision, or chemical processes.

Usage
Context Usage
Business
Virtually never used.
Academic
Core terminology in chemistry, biology, microbiology, and chemical engineering labs and textbooks.
Everyday
Only in contexts discussing school science, university labs, or popular science media.

Examples
By Part of Speech
verb
British English
- The suspension was Erlenmeyer-flasked for the duration of the experiment.
American English
- They Erlenmeyer-flasked the culture medium prior to inoculation.
adjective
British English
- The Erlenmeyer-flask design is optimal for preventing splashes.
American English
- We need an Erlenmeyer-flask setup on that stir plate.
Examples
By CEFR Level
- We used an Erlenmeyer flask in our school science experiment.
- Please pass me the 250 ml Erlenmeyer flask from the shelf.
- After adding the solvent, swirl the Erlenmeyer flask gently to ensure complete dissolution of the compound.
- The baffled design of the Erlenmeyer flask is critical for ensuring adequate oxygen transfer in microbial fermentations.
Learning
Memory Aids
Mnemonic
Imagine the name 'Erlen-MEYER' – it sounds like 'earn a MEASURE', which you do with this precise flask.
Conceptual Metaphor
SCIENTIFIC INQUIRY IS CONTAINED IN GLASS (The flask as a vessel for ideas, reactions, and discovery).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'flask' as 'фляжка' (canteen) or 'термос' (thermos). The correct equivalent is 'колба Эрленмейера' or simply 'коническая колба'.
Common Mistakes
- Mispronouncing as 'Earl-en-meyer'.
- Confusing it with a beaker (which has straight sides) or a volumetric flask (which has a long, narrow neck for precise measurement).
- Misspelling as 'Erlenmyer' or 'Erlemeyer'.

FAQ
Frequently Asked Questions
It is named after the German chemist Emil Erlenmeyer (1825–1909), who designed it in 1860.
Yes, if it is made of borosilicate glass (like Pyrex), it can withstand direct heat. However, flat-bottomed flasks require a gauze mat for even heating on a Bunsen burner.
An Erlenmeyer flask is for mixing, heating, and storing; its volume markings are approximate. A volumetric flask has a single, precise graduation mark for preparing solutions of an exact concentration.
The narrow neck allows it to be stoppered easily, reduces evaporation, permits safe swirling of contents, and facilitates pouring without drips.
