Thermal Gradient Ring system. The Thermal Gradient Ring viewed from above (left) and a schematic representation of the temperature gradient zones with cooler and warmer temperatures shown in blue and red, respectively (right). Two temperature control devices under the ring create a thermal gradient on the floor of the apparatus. There are 12 zones on one half of the ring. These zones and the gradient are duplicated on the other half
