The original custom olfactometer was developed by Johann Lundstrom at the Monell Chemical Sciences Center in Philadelphia.* Whiff has built these devices for researchers in Europe and the US. We source and use commercially available parts, and will happily give you parts lists, assembly diagrams and vendors. Truthfully, these devices are intricate but not complicated. The hard part is the time and effort that goes into doing anything for the first time. We'll do that for you!
