A tall, horizontally subdivided or packed column for fractional distillation, in which vapor passes upward and condensing liquid flows downward. The vapor becomes progressively enriched in more volatile components as it ascends, and the less volatile components become concentrated in the descending liquid.

Common packing materials for stills include glass marbles, raschig rings, copper plumbing elbows and others.
