Selectively heatable substance carrier

The invention relates to a selectively heatable substance support (1) that is heated by means of heat conductors (5) introduced into said support and at least temporarily linked with a heat source (6), or that is specifically heated by heat sources (6) introduced into said support in the zone of the contact surfaces (4), whereby substances that are applied to the contact surfaces attain the desired temperature in less time. A combination of the substance support (1) comprising heat conductors (5) of equal heat conductivity with one or a plurality of separately regulated or controlled individual heat sources, for example a combination of the substance support (1) with heat conductors (5) of varying heat conductivity with a homogeneous heat source (6) or the introduction of a plurality of heat sources (6) that are heat-insulated from one another into the substance support (1) allows heating or adjusting the temperature of the individual contact surfaces individually or in groups.
