Abstract
The spinning disc centrifuge rotor includes a sample holder formed from a cylindrical disc body and a cover plate that are made from a transparent material, such as polycarbonate. The disc-shaped body has two concentric or coaxial recesses defined therein. The first recess forms a cylindrical well or sample chamber for receiving a generally cylindrical rock sample. The second recess has a larger diameter than the first recess, and is shallower, forming a fluid collection area above the sample well, the second recess forming an annular ring extending around the top edge or rim of the sample well. An O-ring snugly within the outer wall of the second recess and forms a seal between the cover plate and the floor of the second recess, preventing fluid leakage. A rotor shaft extends from the bottom face of the cylindrical disc.
