ABSTRACT:
A modular spacer concept is disclosed for use in centrifuge bores. The arrangement is such that various sizes of tubes are available to allow for different amounts of fluid which may be inserted therein for centrifugation. A plurality of substantially identical spacers are provided, each of which has an effective length equal to a predetermined standard difference in tube sizes. The lower surface of each spacer has a concave center portion adapted to fit the convex center portion of the upper surface of a tube, and the upper surface of each spacer has a convex center portion adapted to fit the concave center portion of the lower surface of a substantially identical spacer.
