The Y-Tube Olfactometer – Stem 30 mm | Arm 30 mm is a precision laboratory setup engineered to evaluate insect olfactory behavior under controlled experimental conditions. Built around a high-quality glass Y-tube assembly, the system enables insects to choose between two odor sources, allowing detailed analysis of attraction, repellency, and preference behavior.
The Y-tube features a 30 mm diameter stem and two 30 mm diameter arms, with a stem height of 120 mm, arm height of 80 mm, and a 45° arm angle. These dimensions are specifically designed to promote smooth airflow transition, minimize turbulence, and support natural insect movement, ensuring high repeatability and reliable behavioral observations.
Chemically inert PTFE air connectors and silicone tubing prevent contamination or adsorption of volatile compounds, maintaining the integrity of odor stimuli throughout experimental trials.
A dedicated air pump suitable for Y-tube applications delivers stable and continuous airflow. Two precision air flow control meters (0.1–1 LPM each) allow independent adjustment of airflow in each arm, ensuring balanced and reproducible experimental conditions.
The setup includes two glass jars for air purification and humidification, which remove unwanted VOCs and condition the incoming air to maintain natural insect behavior and experimental consistency. Each jar is designed with a merged inlet and outlet single-head configuration to simplify setup and minimize leakage.
Additionally, two glass volatile collection jars with merged inlet and outlet ports allow controlled introduction of odor sources or collection of emitted volatiles during experiments, supporting advanced research in chemical ecology and insect behavior.
This Y-tube olfactometer system is widely used in entomology, chemical ecology, integrated pest management studies, behavioral bioassays, and insect–plant interaction research. Its modular design enables easy cleaning, flexible configuration, and long-term reliability for academic, institutional, and industrial laboratories.
