This odor delivery system is based on the setup originally described and implemented in Shusterman 2011. It allows presentation of variable number odorants at different concentrations. The fast and temporally precise presentation allows performing sniff based closed-loop experiments. The main principle is based on air dilution via Mass Flow Controllers.
Each extension cassette allows the addition of extra 4 odors to your olfactometer. Electrical circuit supports up to 8 cassettes, however we recommend to have no more than 3 cassettes per each line to avoid a significant pressure increse.
