Abstract

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.
