Classification: CPC G  H | IPC G  H

Claim 21:
22. The apparatus of claim 1, wherein the apparatus comprises a thermal buffer casing and wherein a door assembly is located between the adjacent thermal buffer casing and test zone casing, wherein the door assembly comprises:
a first door which comprises a planar body sized and shaped to cover a slot of the thermal buffer casing and a second, opposing door comprising a planar body sized and shaped to cover a slot of the test zone casing;
wherein the first door and the second, opposing door comprise thermal shielding material;
wherein one or more spring elements between the first door and the second, opposing door tension the one or more spring elements in opposing directions against the thermal buffer casing and the test zone casing, with ends of the one or more spring elements being separated from the first door and the second, opposing door by intervening insulating elements;
wherein the one or more spring elements are in connection with an element connected to a push bar, wherein the push bar is in mechanical connection with an actuator such that the push bar can be moved to move the door assembly;
wherein the door assembly is configured such that actuation of the push bar slides the first door and the second, opposing door such that the coplanar aligned slots of the thermal buffer casing and test zone casing are exposed.
