Definitions

  • Figure 5 illustrates an adapter 10" that defines a modification of the embodiment of the invention shown in Figure 3.
  • the tube T" has the form of a test tube, with no constriction present to define a neck.
  • the segments 12", 14" are modified to exhibit indentations 28" similar to those shown in Figure 3, but which correspond in size and shape to the test tube T" over the entire axial length L" thereof.
  • the adapter heretofore described in connection with Figures 7A through 9B for use primarily in a vertical angle rotor is fabricated of a material and in a manner such that the adapter, while under centrifugation, has sufficient strength to withstand the vertical forces Fv (that is, forces that act parallel to the central axis of the adapter). Vertical stresses in the tube T are therefore minimized.
  • Angled mating edges on the adapter segments are provided to prevent a separation from forming between the segments in response to the radial expansion of the tube under pressure. The prevention of such a separation insures that the tube is supported about the entirety of its circumference such that the possibility of tube failure is minimized.
  • FIG 10 illustrates a preferred arrangement of a split adapter 10 4 for use in a vertical angle rotor in accordance with this embodiment of the present invention.
  • the structure of the adapter 10 4 is generally similar to the adapter 10' shown and discussed in connection with Figures 3A and 3B and to the adapter 10 3 shown and discussed in connection with Figures 7A and 7B in the sense that the adapter 10 4 , like the adapters 10' and 10 3 , is arranged to totally surround a tube T disposed there within.
  • each extension 58 4 , 60 4 serves to frictionally interact with the boundaries of a rotor cavity 42 v ( Figure 11 A through 11C) to prevent rotation of the adapter 10 4 about its axis lO- ⁇ A with respect to the body of the rotor 40 v thereby to maintain the adapter 10 4 in a predetermined angular orientation within the cavity during operation of the rotor.
