Story
During the mid-century boom of American chemical research, this tank was an essential tool for Thin Layer Chromatography (TLC), a process used to separate and identify complex mixtures.
Maker / Origin
Corning Glass Works, founded in 1851, changed the world in 1915 with the introduction of Pyrex—a low-expansion borosilicate glass originally developed for railroad lantern globes.
Condition & Value
The glass appears exceptionally clear with no visible 'clouding' or chemical etching, which often plagues used labware. Value is driven by the crossover market between scientific collectors and interior designers.
