Abstract

A centrifuge rotor comprises a base member and a cover member and has axially-disposed rotational drive connection means in a central region thereof, the base member comprising an essentially circular plate having sample tube locating means disposed radially and terminating outwardly in resilient elements, and the cover member having a lower surface which cooperates, in use, with the base to retain sample tubes securely in position, one of the base and cover members including a least one annular groove disposed radially outwardly of the sample tube locating means and the other of the base and cover members including a corresponding annular projection, the projection being sealingly engageable within the groove when the base and cover members are located together for use. The base member is provided with marked annular zones indicating ranges of packed cell volume and the cover member is transparent, whereby the packed cell volume can be assessed by unskilled personnel in developing countries by direct reading through the cover member against the annular zones, thereby enabling anaemia to be quickly and accurately diagnosed. <IMAGE>
