Patent ID: 7118709

Claim:
A method for tempering at least one specimen, wherein a plastic-based electrically conductive material of a specimen carrier ( 1 , 14 ) 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 ( 1 , 14 ), wherein a volume of the specimen is capacitively measured on the specimen carrier, wherein at least one capacitive measuring sensor ( 17 ) of the specimen carrier ( 14 ) which is associated with a memory location and/or a volume( 15 ) for a specimen and is connected to a capacitance measuring circuit for a capacitive measurement, and wherein the at least one capacitive measuring senor ( 17 ) has capacitator plates formed by the plastic-based electrically conductive material of which the specimen carrier ( 14 ) is partially made are connected to the capacitance measuring circuit for a capacitive measurement.
