A fluid delivery system includes a laboratory instrument that operates using fluid retained in one or more containers. The containers are supported on a motor-driven lift that is configured to transport the containers between a lowered position suitable for handling and an elevated position suitable for the delivery of fluid to the instrument by gravity. The lift includes a bench-mountable base, a tubular column extending upward from the base, an elongated lead screw extending longitudinally through the column, a drive mechanism for rotatably driving the lead screw, a carriage slidably mounted over the tubular column and mechanically coupled to the lead screw, a platform removably coupled to the carriage for supporting the containers, and a control system for regulating operation of the drive mechanism. During operation, a slot provided in the column restricts travel of the platform along a predefined path that is linear in part and helical in part.
