ABSTRACT:
An air sampler includes a stand for supporting a plurality of sample enclosures from which samples can be randomly and selectively obtained. In a first embodiment, a bracket adjustably fixed to the stand supports each of the sample enclosures. In a second embodiment, an inlet line fluidly couples each of the sample enclosures to a valve carried by the stand. The inlet line has a flexible portion adjacent the end coupleable to the sample enclosure to allow limited misalignment between the sample enclosure and the stand.
