Zusammenfassung:	Disposable reaction packs for use in automatic analysis equipment are known. These packs comprise a body which is divided into successive chambers, each of which contains a fluid. Mixing of the fluids in such packs is achieved by manually applying pressure to each chamber of the reaction pack to open the seal between each chamber. This process is time-consuming, inaccurate and could result in damage to the reaction pack. Described herein is apparatus (10) for transferring liquid from one chamber to another in successive chambers of a chemical reaction pack (12). The apparatus (10) comprises a support surface (16) on which the packs (12) are placed, and a plurality of pressure applicators (20) which are driven to apply pressure to the packs (12). Temperature control elements (70) are also provided to heat and cool the liquid contained within each chemical reaction pack (12).
