Pycnometers (4)
notes: label: Description
content: Box of four glass instruments designed for determining the specific gravity of small amounts of liquid. The “Eichorn's araeopicnometer” inscription refers to August Eichorn, of Dresden, who obtained a German patent (DR Pat. 49683) on the form. Instead of floating the instrument in the liquid to be tested, a small amount of that liquid is put into the hydrometer which, in turn, is floated in water.
