This economical package includes everything needed to present olfactory stimuli to a nose poke response or test chamber port (nose poke and port sold separately). This includes two distribution manifolds, three solenoid valves, evaporation jars
with barbed fittings and check valves, and a coil of tubing for connecting these components. The standard package uses two normally closed valves for the odor lines and a normally open valve for fresh air. This maintains a continuous flow of
air at the nose poke port or at a bulkhead port if desired. By activating two valves simultaneously, odor can be added to the air stream without altering the flow. In this way the only stimulus is the odor, not the presence or absence of the airflow. Operating controls and pumps sold separately. Also available with five manifolds (ENV-275-5).

Select from several rat nose poke modules with or without stimulus lights and then add this option to present an odor stimulus inside the nose poke. Two barbed fittings are provided. Attach the second port to a suitable vacuum pump to confine the odor to the nose poke as much as possible.
Dimensions:
Panel: 3.0" W x 3.25" H x 1.0" D
(7.6 cm x 8.3 cm x 2.5 cm)
Special Note:
Nose poke port shown here installed on the nose poke response for rat (ENV-114BM). |

This dilution olfactometer comes with two channels and is expandable to eight channels. It is designed to generate precise concentrations of up to eight separate odors. Airflow to each vertical column saturator is controlled by a sensitive needle valve and monitored by a calibrated flow meter. Valves activated by 28 V DC solenoids are used to mix odors and route airflow to the test chamber. This system is suitable for odor discrimination tasks where flow control is critical, olfactory coding, or any behavioral or neurophysiological study that uses odor as a stimulus.

This expansion olfactory column saturator connects to the dilution olfactometer (PHM-275). Air flow is controlled by a sensitive needle valve and monitored by a calibrated flow meter. Flow out of the column saturator is controlled via a 28 V DC solenoid to mix odor.

This 28 V DC exhaust fan is mounted on a 1/4 size rat modular panel to increase airflow though the chamber and clears odors quickly. If using a sound-attenuating cubicle, the cubicle fan ensures an ample supply of fresh air around the outside of the chamber.
