Object Details
- Description (Brief)
- Glinksy’s distilling tube (or dephlegmator) dates from 1875, a time when the burgeoning field of organic chemistry led to a proliferation of distillation apparatus designed for the laboratory. 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.
- A dephlegmator uses separate chambers to promote multiple condensations and vaporizations, leading to a more efficient separation of the components. Glinksy’s dephelgmator features spherical glass beads as separations between its chambers.
