<p>A thermal cycler for performing amplification of nucleic acids, comprising (a) a thermal block (71) having a plurality of chambers; (b) a movable cover (14) having heating means (15) positioned within it; (c) transport means for moving said cover (14) from said first position to said second position and viceversa, the path followed by the cover (14) comprising: a first path segment which lies above and at a predetermined distance from said thermal block (71) and along which said cover (14) is moved towards a stopper (16) until it abuts against it and a second path segment along which said cover (14) is moved away from said stopper (16) and downwards until it is vertically aligned with said thermal block (71) and exerts a predetermined pressure on reaction vessels (13) positioned in said chambers (72) of said thermal block. <IMAGE></p> |
