The Snap & Sniff® threshold test kit is comprised of 20 smell "wands". Five contain no odor, whereas the others contain, in the case of the standard odorant phenyl ethanol, half log dilutions ranging from 10-2 (strongest) 10-9 (weakest) concentrations. When the thumb of the operator pushes a slide mechanism, the odorized tip is exposed for sampling and presentation to the subject. Releasing the slide retracts the odorized tip back into the wand housing. Because the odorant is presented only briefly, it is retained for much longer periods and can be used for testing many more subjects than devices lacking such sophisticated technology.
