<p>There is disclosed a device for selectively maintaining a reactive sample at different temperatures during the course of a reaction, the device comprising: a body having a first part and a second part, at least one of the body parts being moveable relative to the other; at least one sample mount provided in the first body part for mounting the reactive sample therein; temperature control means thermally coupled to the second body part for selectively and independently controlling the temperature of at least two regions of said second body part, said regions being disposed from each other; and means for moving at least one of the first and second body parts relative to the other for enabling said sample mount to expose the reactive sample to said at least two regions that are at different temperatures during the course of the reaction.</p> |
