Distillation Tube
notes: label: Description (Brief)
content: This is a Snyder distillation column. Distillation is the process of separating a mixture of liquids with different boiling points through evaporation and condensation. Liquids with lower boiling points vaporize first, rise through the distillation apparatus, and recondense to be collected in a separate container.
label: Description (Brief)
content: The Snyder column could also be referred to as a dephlegmator, which is a specific kind of distillation column. It utilizes separate chambers to promote multiple condensations and vaporizations during the distillation process, leading to a more efficient separation of the mixture’s components. Snyder’s dephelgmator features lightbulb-shaped glass bubbles as separations between its chambers.
label: Description (Brief)
content: This object was used at the Chemistry department at the University of Pennsylvania. Chemistry has been taught at the University since at least 1769 when doctor and signer of the Declaration of Independence, Benjamin Rush (1746–1813), became Professor of Chemistry in the Medical School. A Chemistry department independent of the Medical School was established by 1874.
