Abstract
A configurable cryogenic storage device has a freezer and a rack carrier positioned inside of the freezer. The freezer includes a bearing and a drive shaft though the freezer, the drive shaft being coupled to the rack carrier inside the freezer and adapted to be coupled to a motor assembly. The rack carrier rests on the bearing in a manual rotation configuration and hangs from the drive shaft when the motor is connected. Coupling the drive shaft to the motor assembly lifts the rack carrier and decouples the bearing and enables automated rotation of the rack carrier by the motor. The rack carrier includes rack-mounting features holding a plurality of sample storage racks. The sample storage racks hang from the rack carrier and the rack-mounting features precisely position the end of each sample storage rack.
