A device for centrifugation and robotic manipulation of specimen samples,
including incubating eggs, and uses thereof are provided. The device may
advantageously be used for the incubation of avian, reptilian or any type
of vertebrate eggs. The apparatus comprises a mechanism for holding
samples individually, rotating them individually, rotating them on a
centrifuge collectively, injecting them individually with a fixative or
other chemical reagent, and maintaining them at controlled temperature,
relative humidity and atmospheric composition. The device is applicable
to experiments involving entities other than eggs, such as invertebrate
specimens, plants, microorganisms and molecular systems.
