A centrifuge tube for collecting and dispensing a mixed concentrated fluid sample. The centrifuge tube has an elongated tube body with an open top end and a bottom end preferably having a dispensing spout. A divider insert is positioned inside the inner volume of the tube body to divide the inner volume into upper and lower chambers. The divider insert has a funnel shape with an inverted conical section and a funnel spout having a spout tip. The spout tip extends into the lower chamber while remaining above the bottom end. Upon filling the upper chamber with a fluid and subjecting it to centrifugal forces inside a centrifuge, a concentrated fluid sample is collected in the lower chamber with an air pocket captured between the spout tip and the divider insert. The concentrated fluid sample may then be agitated to mix the sedimented solids with the liquid of the concentrated fluid sample, and the now mixed concentrated fluid sample subsequently dispensed through the dispensing spout.
