Soxhlet extractor. Franz von Soxhlet was born on 12 January 1848 in Brno, Moravia, Austrian Empire and migrated with his family to the German Confederation.He was the son of spinning industrialist Hubert Soxhlet, an immigrant from Dalhem near Liège (in the former Duchy of Brabant).
Volumetric flask is used for preparing liquids with volumes of high precision. It is a flask with an approximately pear-shaped body and a long neck with a circumferential fill line. Dewar flask is a double-walled flask having a near-vacuum between the two walls. These come in a variety of shapes and sizes; some are large and tube-like, others ...
Dropping funnels are usually constructed with a ground glass joint at the bottom, which allows the funnel to fit snugly onto a round bottom flask. This also means it need not be clamped separately. [1] Dropping funnels have been in use since at least the mid-1800s. [2]
