ABSTRACT:
A breakaway base for use with an ultracentrifuge rotor wherein the base is designed to fracture when the rotor is above a specified speed so that the rotor will disengage from the drive spindle of the centrifuge. The base has cutout areas to establish a high stress region that is designed to fracture above a specified rotor speed. The cutout areas are designed to receive lugs projecting from the bottom of the rotor. The cutout areas have slotted ledges through which fastening bolts connect to the lugs on the rotor. The fracture of the base in the high stress region in conjunction with the slotted ledges will result in the base fracturing into two parts which will cause rotor disengagement from the drive spindle of the centrifuge and prevent the rotor from spinning at a greater speed.
