Abstract
A redundant safety lock for securing a centrifuge lid in its closed position. The lock includes a disc having an aperture through which a striker on the lid can be inserted in an unlocked position. The disc is rotated to a locked position such that the striker cannot be withdrawn through the aperture to open the lid. The weight distribution of the disc is substantially symmetrical about its center of rotation. The disc is therefore less susceptible to dislodging form its locked position upon perturbation from shock experienced.
