Patent ID: 7498831

Claim:
A testing apparatus for executing testing on at least one test subject, comprising: a first set of channels for cooling the at least one test subject by conduction, comprising: at least one first cooling channel operable to receive a supply of liquid nitrogen and further operable to distribute the supply of liquid nitrogen to at least one second cooling channel; the at least one second cooling channel, connected to the at least one first cooling channel, operable to receive the supply of liquid nitrogen from the at least one first cooling channel and further operable to distribute the supply of liquid nitrogen to at least one third cooling channel; and the at least one third cooling channel, connected to the at least one second cooling channel, operable to receive the supply of liquid nitrogen from the at least one second cooling channel and further operable to cool by conduction a structure that is operable to cool by conduction the test subject; and a second set of channels for heating the at least one test subject by conduction, comprising: at least one first heating channel operable to receive at least one heating rod and further operable to heat by conduction a structure that is operable to heat by conduction the at least one test subject.
