ABSTRACT:
A rheometer die assembly includes a lower oscillating or rotating die adapted for engagement with a stationary upper die. The lower die has an O-ring circumferentially positioned about a top surface thereof and in alignment with an annular planar sealing surface in the upper die. Engagement between the sealing surface and the O-ring defines a cavity between the two dies. A groove about a circumferential edge surface of the lower die is exposed when that die is received in a holder, such groove accepting the insertion of a tool for removing the die from the holder.
