A self-adjusting pick-up tube assembly for aspirating liquid from containers of varying heights. Such assembly comprises (a) a platform member adapted to be positioned in contact with the bottom of a container when the pick-up tube is being used to aspirate liquid from such container; (b) a disk-shaped member adapted to be retained in a position proximate the container's liquid filling aperture when the pick-up tube is in use; (c) a flexible conduit interconnecting respective liquid passageways in the platform and disk-shaped members, and (d) a telescopic mount for enabling relative movement between the platform and disk-shaped members to accommodate containers of different height.

[ What is claimed is:] [1.] A pick-up tube assembly for aspirating a liquid from a liquid-containing container having a filling aperture in a wall thereof, said assembly comprising:(a) a platform member adapted to be positioned in contact with the bottom of a container at a location substantially opposite the container's liquid access opening when the pick-up tube is being used to aspirate liquid from such container, such platform having a liquid passageway extending between a pair of surfaces thereof;(b) a disk-shaped member having opposing surfaces and means defining a liquid passageway between such surfaces, such disk-shaped member being adapted to be retained in a position proximate the container's liquid access opening when the pick-up tube is in use;(c) a flexible conduit interconnecting the respective liquid passageways in the platform and disk-shaped members, such flexible conduit being capable of conducting liquid from the container; and(d) mounting means for movably mounting the platform member for movement relative to said disk-shaped member to enable said platform member to move towards and away from said disk-shaped member.
