ABSTRACT:
A centrifuge tube with temporary liquid storage cavities. The centrifuge tube has an upper opening and defines a specimen enclosure therein. The tube includes a lid for sealably covering the upper opening. Temporary liquid holding cavities are formed upon the underside of the lid so as to extend outwardly from the underside and terminate in open distal ends. One or more liquid components or reagents can be inserted directly into the open distal ends of the cavities so as to reside inside the cavities on the lid. The cavities are sufficiently narrow so that the walls of each cavity are disposed in frictional engagement with the liquid to increase the surface tension and adherence of the liquid within the cavity. The lid can be snapped shut over the opening of the tube without discharging the liquid components from the cavities, so that the liquid components hang in open suspension above the bottom of the tube. The liquid components are dislodged from the cavities and fall to the bottom of the tube upon centrifugation of the tube.
