Olfactory stimulus is available with the five nose poke wall with stimulus lights. This modified wall (ENV-115A-OF for rat and ENV-115C-OF for mouse) allows individual olfactory stimulus in each nose poke. A pressurized laboratory air supply or air pump (sold separately) provides air to each individual scent source. A check valve between the one-to-five manifold and the scent source container prevents the mixing of scents when the system is not pressurized. A normally closed valve prevents the scent stimulus from reaching the nose poke until the valve is activated. Only one scent source is connected to each nose poke. Activation of the control valve allows the olfactory stimulus to be presented in the nose poke. One or more of the valves may be activated at the same time depending on the protocol of the experiment. The olfactory stimulus is removed from the nose poke cavity via an exhaust port located in the roof of the cavity. All five nose pokes are connected to a five-into-one manifold that is to be connected to a vacuum pump (sold separately). This system provides continuous evacuation of air from all five nose pokes simultaneously when connected to a vacuum source. An extra grid rod which cannot be used for aversive stimulus has also been added to fill the gap formed by
the curved wall.
Interface, computer and software are sold separately.
Features:
- Individual olfactory stimulus in each nose poke.
- Check valves prevent the mixing of scents.
- One or more valves may be activated at the same time.
- Olfactory stimulus is removed from the nose poke via an exhaust port.

Olfactory Stimulus Components

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.

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.
Dimensions:
13.8" L x 15.0" W x 11.5" H
(35.0 cm x 38.1 cm x 29.2 cm) |

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.
Dimensions:
3.375" W x 2.5" D x 11.0" H
(8.6 cm x 6.4 cm x 27.9 cm) |

This bulkhead port is mounted on a 1/8 size rat modular panel with a small air port and barbed fitting for presenting odors to the chamber compartment. This could be placed above or below any other modular panel such as a response lever or food cup.
Dimensions:
Panel: 3.0" W x 1.625" H (7.6 cm x 4.1 cm)
This bulkhead port is mounted on a 1/4 size mouse modular panel with a small air port and barbed fitting for presenting odors to the chamber compartment. This could be placed above or below any other modular panel such as a response lever or food cup.

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.
