A reaction device is provided with a first wall that defines an interior in which a stirring mechanism is located. A heat exchanger is at least partly provided on the first outer wall surface facing away from the interior and/or on the stirring mechanism, wherein the heat exchanger has a grate structure, and at least two layers are provided which have a grate structure. Thus, it is possible to transfer heat in a precise and efficient manner primarily by means of thermal radiation in endothermic processes at different temperature levels, in particular pyrolysis, gassing, and reforming processes, and thereby use the exhaust heat for other processes.

A sample heating/cooling device (2) comprises a plurality of members (6) operable in use to heat and/or cool one or more samples (22). Each member (6) has a sample contact surface and is biased towards a resting position under the operation of a biasing means. The members (6) are movable independently of one another against said bias under the application of a force on the sample contact surface and so are able to conform to the shape of a sample placed on the members to provide a uniform heating/cooling profile. The members (6) may be mounted in a heating/cooling element (4) and adapted to conduct thermal energy between the sample (22) and the element (4). The device (2) is particularly suitable for thawing frozen sample bags having an irregular shape. A corresponding method is also described.
