Some embodiments of the present invention provide an apparatus (1) comprising at least one receptacle (42) within which an article (44) can be placed for temperature-controlled storage. The apparatus (1) has a reservoir (10) within which fluid is contained, the reservoir (10) having a cooling region in thermal communication with the at least one receptacle (42). The reservoir (10) includes a headspace containing fluid that is, in use, higher than the at least one receptacle (42). The apparatus (1) has cooling means (30) for cooling fluid within the headspace. The or each receptacle (42) comprises a tube or pouch having an opening defined by an aperture (40) disposed in a wall of the reservoir (10) and extending inwardly into the cooling region so as to be submerged therein.
