Patent ID: 7485262

Claim:
A sampling wand for use in a device for a chemiluminescent assay of microbial species on a solid surface, the wand comprising: (a) an internal reservoir disposed toward a distal end of the wand; (b) a frangible seal on a bottom surface at a distal end of the wand in fluid communication with the internal reservoir to seal a reagent rinse solution within the reservoir; (c) an external sampling swab comprised of a disc of porous, absorbent polymeric material disposed on the bottom surface at the distal end of the wand with the frangible seal interposed between the sampling swab disc and the reagent reservoir for picking up the microbial species or cellular material from the species upon the surface; (d) an o-ring positioned toward the distal end of the wand being adapted to form a sealing fit between the wand and an internal wall of an inner chamber of a sampling analysis member as the wand moves longitudinally through the inner chamber; wherein when the seal is broken the reagent rinse solution rinses through and from the sampling swab disc to release the microbial species or the cellular material from the sampling swab disc for the assay in the device.
