ABSTRACT:
A device for tempering and/or sterilizing objects which must be kept free of contamination by foreign particles, such as for example, ampules sterilized in pharmaceutical preparations, has a housing and means for supporting the objects in the housing. A pair of gas distribution plates are mounted in the housing in spaced relationship to each other, on either side of the support means, and cooperate with means for supplying conditioned air to produce a laminar flow of the conditioned air downwardly over the objects being treated. The conditioned air has a substantially different temperature than the objects being treated and can be either heated or cooled depending upon whether the device is used for sterilizing or tempering. Because of the maintenance of laminar flow in the housing, the number of contaminating particles per space unit which can come into contact with the objects being treated is decreased.
