Abstract
An air sampler mechanism by which the entirety of the petri plate assembly of the air sampler may be easily removed without tools is described. The mechanism employs at least one magnet which is preferably disposed within the top plate assembly of the air sampler instrument. The magnets of the mechanism are configured to maintain the top plate assembly firmly in position during use while facilitating easy removal by an operator or manager. Indexing features are preferably present, which ensure proper alignment and positioning of the top plate assembly when reattached for use.
