A nutatable plastic vessel, having a protuberant tip at its bottom end, has its side wall connected by a plastic hinge to a housing.

Vortexing liquid container

A lid structure for a polypropylene container is formed of a three ply laminate and a rehealable silicone rubber top layer adhered to the laminate. The laminate is polyester, polyvinylidene chloride and polypropylene heat sealed to the top rim of the container.

Lid structure

An automatic vortexing drive is described in which a rotatable coupling has a cuplike recess positioned off of and opening radially outward from the axis of rotation of the coupling. The coupling is positioned to intercept the lower and reaction vessels in the recess. Selective rotation of the coupling permits the vessels to pass the coupling or be engaged by the coupling and nutated.

Vortex mixer drive

A vortexing mixer drive has a rotatable coupling rod where an end face defines an offcenter countersink with a bore at the center of the countersink. The rod is axially displaced to engage a vessel's protuberant tip to effect rotational movement.
