Methods to develop a low cost laboratory olfactometer for multisensory, psychology, and neuroscience experiments

Olfactometers are kind of machines specially designed to deliver different odorants to the users, based on a timely protocol. Purchasing off the shelf systems are expensive and require additional customizations according to the type of the experiments they will be used for. In order to facilitate smell, taste, psychology, and neuroscience experiments we have developed our own laboratory olfactometer from the scratch. This paper provide a complete overview of the design and development process of our laboratory olfactometer. The key novelty of our work is the development of low cost, flexible, and easy maintenance olfactometer. Further, this olfactometer provides rich functionalities such as seven odor channels and a control air channel, flow controlling for the overall system and individual channels, air pressure control, air filtration, back flow prevention, and continuous operation of more than 8 hours.
