ABSTRACT:
A culture blending vessel adapted for the preparation and containment of samples for microbiological analysis which includes a vessel body and a rotor assembly. The mouth opening of the vessel body is closed by a lid which threads onto the top of the vessel. The rotor assembly has a rotatable shaft extending through a port in the cylindrical side wall of the vessel body. Blending knives are fastened to the interior end of the shaft and may be used to blend the contents of the container by coupling the exterior end of the shaft to a blending motor. The blended sample may then be incubated without transfer to a separate culture vessel.
