Refill threshold smell test n-butanol
The question which you have to ask the test subject is: From which concentration on can you perceive an odorant (n-butanol)? Repeatedly, three pens will be presented to you one after another. Only one of these pens contains the odorant, the other two contain just water. You have to find out the pen in which you think you have perceived the odorant. In any case, you have to pick one of the three pens, even if you are not sure with your decision.
N-butanol or 2-phenylethanol version
The Sniffin’ Sticks threshold test is available in 2 versions with only one difference: the smell of the target pen. The 2-phenylethanol version has a rose smell (and is therefor also known as the rose version) and the n-butanol version has an alcohol like smell.
Another difference is that the 2-phenylethanol version has a longer expiration date (1,5 year) compared to the n-butanol version (7-8 months). This is because the n-butanol substance is very volatile.
Due to hygienic reasons and the expiration date of these tests we cannot accept returns of the sticks.
