Mary the Jewess

The German chemist Franz von Soxhlet modifies the kerotakis, an alchemical device attributed to Mary the Jewess, to create the Soxhlet extractor, an apparatus widely used for extracting lipids from a solid material. This date marks a significant moment in the evolution of laboratory equipment, tracing back to the innovations of an early alchemist. Soxhlet's modification allowed for continuous extraction, improving the efficiency of lipid extraction processes.
