ABSTRACT:
The present invention relates to heating of samples in specimen carriers, and more particularly to the heating of zones of a specimen carrier for differential heating of samples in a specimen carrier, including a specimen carrier in the form of a metallic sheet, in which a matrix of sample wells is incorporated, apparatus for applying electrical heating current through the carrier, having a plurality of electrical current sources, each connected in series across the carrier and together providing a variety of different possible current flow paths whereby localised regions of the carrier may be selectively heated. The current applied is either alternating current, or direct current.
