What it is
Dutch pharmacist Kipp designed a laboratory gas generator with three stacked glass chambers that produces gas on demand by bringing a solid into contact with an acid, and automatically stops the reaction when the outlet is closed.
Wikidata gave 1860 as the year; several sources place the original design around 1844, though it was popularized and refined in the following decades.
What it led to
- Safe generation of gases such as hydrogen sulfide or carbon dioxide in the lab
- Widespread use in chemistry teaching well into the 20th century
- Gradual replacement by compressed gas cylinders
