Described is an apparatus for simultaneously sterilizing a large number of packs (1) by means of a gas mixture containing hydrogen peroxide and a carrier gas. The apparatus comprises: supply lines (4) for the carrier gas and for hydrogen peroxide (5), a device (21) for evaporating hydrogen peroxide by heat and mixing it into the carrier gas, supply lines (4, 5) and a substantially horizontally extending distributor line (6, 22) and nozzles (3) which are arranged above the respective pack (1) and are connected to the distributor line (6, 22). In order simultaneously to provide, with a simplification in the apparatus, measures by means of which the concentration of the hydrogen peroxide at all nozzles is maintained equal over the plurality of packs at a given time, the invention provides that the distributor line (6, 22) from the upstream location (23) of the in-feed of the conditioned gas mixture to the location (9) of entry upstream of the respective nozzle (3) is in the form of a tubular body including a longitudinal passage, with at least one substantially tubular heating cartridge (18) extending over the length of the tubular body and distributed measurement points (12) and that the heating cartridge (18) is divided into at least two portions and can be heated controlledly by a supply of electrical energy in such a way that the temperature at the outer ends of the tubular body (6) differs from the temperature at the center. |
