A method for changing the temperature of one or more biological specimens from an initial temperature to a final temperature, comprising: providing at least two temperature control plates defining a space therebetween, a first temperature control plate having a first inner surface and the second temperature control plate having a second inner surface providing one or more heat conducting structures, each having a first outer surface and a second outer surface spaced from said first outer surface by a body of the heat conducting structure, said body having at least one channel extending along at least a portion thereof placing said biological specimens received within a container within at least one of said channels placing said heat conducting structures within said space such that said first outer surface is in contact with said first inner surface of the first temperature control plate and second outer surface is in contact with said second inner surface of the second temperature control plate and changing a temperature of at least one temperature control plate from an initial temperature to a final temperature changing thereby a temperature of said heat conducting structures and biological material specimens received therein.La présente invention se rapporte à un procédé destiné à changer la température dun ou de plusieurs échantillons biologiques, dune température initiale à une température finale, comprenant les étapes consistant à : utiliser au moins deux plaques de régulation de température délimitant un espace entre elles, une première plaque de régulation de température comportant une première surface intérieure et la seconde plaque de régulation de température comportant une seconde surface intérieure utiliser une ou plusieurs structures de conduction thermique, chacune comportant une première surface extérieure et une seconde surface extérieure espacée de ladite première surface extérieure par un corps de la structure de conduction thermique, ledit corps
