Pycnometer
notes: label: Description
content: A pycnometer (sometimes termed a Geissler specific gravity bottle) is a glass flask with an accurate and delicate thermometer, that determines the density of a liquid and how it varies with temperature. The form was devised in 1859 by the German glassworker, Heinrich Geissler (1814-1879) and the Russian chemist Dmitri Ivanovich Mendeleev (1834–1907). The “Jenaer Normalglass Germany” inscription on the thermometer of this example refers to the Jenaer Glaswerk Schott and Genossen, a firm established in 1884.
