In-Line Olfactory Evaporation Chamber
Product #: H15-20
|
These chambers have an inlet and outlet barb so that clear air (or any other gas) may be passed through them. The volume is sufficient to minimize flow-through dilution gradients for typical cuing presentations.
A small amount of liquid or a swab of cotton with the proper amount of olfactant is placed in the chamber. The olfactant evaporates int the air in the chamber. When the solenoid valve is opened, air (or other gas) bearing the (solute) olfactory stimulus is delivered. With a small percentage of the total volume delivered, the concentration gradient over the flow interval is minimized.
A check valve is supplied with each chamber to prevent back-flow cross contamination of the olfactants in each chamber. See also the H15-03 Olfactory Stimulus Control.
