kipp's apparatus
Very LowTechnical/Scientific
Definition
Meaning
A laboratory device for generating gases by the reaction of a solid with a liquid, typically consisting of three stacked glass bulbs.
A historical piece of chemistry equipment used to produce a continuous supply of gas (like hydrogen sulfide or carbon dioxide) on demand, now largely replaced by modern gas cylinders and generators.
Linguistics
Semantic Notes
The term is highly specific to historical and educational chemistry contexts. It is a proper noun (capitalized 'Kipp's') referring to a specific invented apparatus.

Examples
By CEFR Level
- We saw an old Kipp's apparatus in the science museum.
- The chemistry teacher demonstrated how Kipp's apparatus could generate hydrogen sulfide safely.
- Although largely obsolete, Kipp's apparatus remains a classic illustration of principles in continuous-flow chemical engineering.
Learning
Memory Aids
Mnemonic
Think of a 'KIP' of gas: Kipp's Apparatus Produces gas in a continuous drip.
Conceptual Metaphor
A TOOL AS A SERVANT (it produces gas on demand).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'apparatus' as 'аппарат' in a broad sense; it is specifically 'прибор' or 'аппарат Киппа'.
- Do not omit the possessive 's' (Kipp's, not Kipp).
Common Mistakes
- Misspelling as 'Kip's apparatus' or 'Kipps apparatus'.
- Using it as a general term for any lab equipment.

FAQ
Frequently Asked Questions
It was invented by the Dutch pharmacist Petrus Jacobus Kipp in the 19th century.
Rarely. It is mainly of historical interest or used in educational demonstrations, having been superseded by safer, more convenient gas cylinders and generators.
Commonly for generating hydrogen sulfide (H₂S), carbon dioxide (CO₂), and hydrogen (H₂).
The design allows a solid reactant (in the middle bulb) to be exposed to or isolated from a liquid acid (in the top bulb) to start or stop the gas production, with the bottom bulb collecting spent liquid.
