Abstract
A unitary centrifuge tube and separable sediment dispenser comprises a generally tubular portion with a conical taper connected by a short tube to a sediment receptacle. The receptacle is designed to be easily separated from the centrifuge tube by twisting the receptacle and centrifuge tube with respect to each other. A short segment of the connecting tube which remains attached to the sediment receptacle allows convenient dispensing of the enclosed sediment by squeezing two opposed walls of the container. A second pair of opposed transverse sidewalls is designed to resist flexing during the separation.
