DEVICES AND METHODS FOR OVERLAYING BLOOD OR CELLULAR SUSPENSIONS

摘要: A device is described that overlays a first fluid, such as blood or cellular suspension onto base material, Ficoll liquid density gradient. In some embodiments, the fluid layering includes cylindrical reservoir, barrier, coupling extension, one more helical channels in communication with and an exhaust vent. The can be coupled through its extension to open end of container, conical centrifuge tube, including material. Once attached, regulates flow from reservoir into tube so suitable overlay formed without substantially disturbing surface regardless care skill user.
