Abstract

An apparatus (10) for testing at least one article (160) comprises a first chamber (20) having a controllable first environment, a second chamber (30) having a controllable second environment, and an intermediate housing (40) connected between the first and second chambers. The intermediate housing (40) defines a work space (54) and includes a window (70) which provides access to the work space. A rotatable container (100) is disposed in the work space (54) and defines a test chamber (110) in which the at least one article (160) is placed. The container (100) is rotatable between a first position in which the test chamber (110) is exposed to the first environment and is thermally insulated from the second environment, a second position in which the test chamber (110) is exposed to the second environment and is thermally insulated from the first environment, and a third position in which the test chamber (110) is accessible through the window (70) in the intermediate housing (40).
