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.

A centrifuge tube comprising: a tube body defining a specimen enclosure therein and having an open end and an opposing closed end; lid means for removably covering the open end of the tube body; and liquid-holding cell means formed on the lid means and terminating in an open distal end for holding a liquid component therein even when the open distal end is facing downwardly, said liquid-holding cell means being disposed such that said distal end faces the specimen enclosure when the lid means is covering the open end of said tube body; wherein the lid means and the liquid-holding cell means collectively comprise capping means including: a cap member having opposing upper and lower surfaces; a hollow holding cell extending outwardly from the lower surface of the cap member and terminating in an open distal end; wherein the hollow holding cell includes interior side walls, said centrifuge tube further comprising at least one sector wall attached at opposing edges thereof to opposing portions of the interior side walls of the cell so as to extend across the hollow cell and divide the cell into a plurality of holding sectors configured to hold corresponding plurality of liquid components in isolation from contact with each other.
