Abstract
A thermocycler has, as heating devices, a plurality of heating blocks each with a respective coupling face, for heating at least one stationary specimen that during one temperature cycle has a plurality of temperature levels. The plurality of heating blocks is pivotably disposed, and the pivot axis is oriented perpendicularly to the coupling faces. The thermocycler is especially well suited for performing the polymerase chain reaction.
Claims19
A thermocycler having a plurality of heating devices for heating at least one stationary specimen that during one temperature cycle has a plurality of temperature levels, the plurality of heating devices comprising;
- movable heating blocks, each of the plurality of heating blocks provided with a coupling face for heating the stationary specimen,
- wherein each of the plurality of movable heating blocks is pivotably disposed about a pivot axis, the pivot axis being oriented perpendicularly to the coupling faces of the plurality of heating blocks, and
- wherein the heating blocks are displaceable perpendicularly to a respective coupling face via a hoisting device, the hoisting device comprises a deflection lever.
A thermocycler having a plurality of heating devices for heating at least one stationary specimen that during one temperature cycle has a plurality of temperature levels, the plurality of heating devices comprising:
- movable heating blocks, each of the plurality of heating blocks provided with a coupling face for heating the stationary specimen,
- wherein each of the plurality of movable heating blocks is pivotably disposed about a pivot axis, the pivot axis being oriented perpendicularly to the coupling faces of the plurality of heating blocks, and
- wherein the heating blocks are displaceable perpendicularly to a respective coupling face via a hoisting device, the hoisting device comprises a tension magnet.
A method for heating a specimen in a thermocycler, having a plurality of heating blocks for heating at least one specimen that during one temperature cycle has a plurality of temperature levels, the method comprising:
- moving the plurality of heating blocks, each of the plurality of heating blocks provided with a coupling face for heating the specimen;
- and
- setting a temperature difference between the specimen to be heated by one of the plurality of heating blocks and the corresponding heating block before the specimen is put into contact with the coupling face of the corresponding heating block different than a temperature change in the specimen to be effected.
