Laboratory module for performing experiment for animal husbandry, has inner wall with controllable aperture, so that definable amount of air flows from inner space into intermediate space per time unit

摘要

The module (1) has an inner wall (10) surrounding an inner space (I) of the module. An outer wall (20) surrounds the inner wall. The walls define an intermediate space (Z). A suction unit (30) suctions off air present in the intermediate space, so that low pressure prevails in the intermediate space opposite to an outer space surrounding the module. The inner wall comprises a controllable aperture (O), so that a definable amount of air flows from the inner space into the intermediate space per time unit. The unit comprises an ultra filter (31) to led the sucked off-air into the outer space.
