Abstract
A method for tempering at least one sample wherein an plastic-based electrically conductive material of a specimen carrier consisting at least partially of this material for at least one specimen is applied to by an electric current/an electric voltage which causes a resistance heating of at least one portion of the plastic-based electrically conductive material, which resistance heating heats a specimen disposed on the specimen carrier.
