ABSTRACT:
A centrifuge rotor head has a hollow frusto-conical housing with parallel inner and outer, upwardly and inwardly inclined walls joined at top and base ends by top and bottom annular flanges, and closed at the top by a central horizontally extending disc portion. The top flange is interrupted at equiangularly spaced intervals by circular openings which, together with an internal annular chamber, present steep angled cavities making angles of about 20.degree. with the rotor cone axis. The housing is capped at its upper end by a circumferentially-extending crown-shaped ring which has a plurality of upwardly and inwardly inclined projections located radially outward of the openings. The projections support the exposed upper ends of tubes placed in the cavities, to guard against neck breakage and stopper dislodgement during spinning.
