Abstract

A pipette workstation of the type dispensing fluids into a microtiter plate with well closure structures that are thimble-shaped members with ridges that form a seal. The closure structures have a beveled nose lower end for self-centering entry into a well with a lower peripheral ridge acting as a first seal. An intermediate peripheral ridge contacts the wall of the well and forms a second seal barrier. An upper peripheral ridge has a diameter that barely enters the well for wedge action stoppage of entry of closure member into the well and further sealing the well. A pipette head with a nozzle array attaches to an array of seals and inserts the seals into wells. The pipette head uses a vacuum force to remove the seals.
