Abstract
A tube washing system including a tube spinning station having a rotatable chuck and a waste chamber surrounding the chuck for capturing and draining tube fluids expelled from a spun tube driven in rotation by the chuck. The chuck has a body portion and a plurality of spaced apart teeth defining intervening grooves extending through the body portion with at least one of the grooves permitting passage of fluid through the body portion and at least one other of the grooves receives and mechanically connects a projection on an open end of a tube. A pipette for dispensing wash water into a tube is located centrally within the chuck. There is also a tube elevating device located beneath the tube spinning station, the tube elevating device comprising a freely rotatable tube holder, and lift drive motor provided to vertically move the tube holder towards and way from the chuck. The tube used in the washing system has at least one projection provided on its open end which can interlock with a chuck groove. The invention also relates to a method of using the tube washing system to rapidly and efficiently wash a tube and its contents.
