Abstract

See full text

A device is described that overlays a first fluid, such as blood or a cellular suspension onto a base material, such as a density gradient. In some embodiments, the fluid layering device includes a cylindrical reservoir, a fluid barrier, a coupling extension, a plunger, and an exhaust vent. The fluid layering device can be coupled through its coupling extension to an open end of a container, such as a conical centrifuge tube, including the density gradient. Once attached, the plunger may be lowered to a position above the surface of the density gradient. A first fluid may flow from the reservoir into the conical tube across the plunger, so that a suitable overlay is formed without substantially disturbing a surface of the density gradient.
