The Y-Tube Olfactometer for Large Insects is a laboratory-grade instrument developed for entomological research and controlled olfactory experiments involving large insect species. It is widely used to study insect responses to odor stimuli, including attraction, repellency, and behavioral preference in larger and more active insects.

The Y-shaped design consists of a central stem through which insects are introduced, leading to two arms that present separate odor environments. This dual-choice system enables researchers to observe directional movement and analyze insect behavior under controlled airflow conditions.

Manufactured from high-quality borosilicate glass, the olfactometer offers excellent transparency, durability, and resistance to chemical exposure. Its larger dimensions provide sufficient space for insect movement while maintaining stable airflow with minimal turbulence, ensuring reliable and reproducible experimental results.

The availability of multiple variants allows selection based on insect size and experimental requirements. Larger diameters support higher airflow rates, while extended arm lengths provide more time and space for observing behavioral responses.

The transparent construction allows clear observation of insect movement, and the design integrates seamlessly with air compressors, airflow controllers, charcoal filters, and humidifier systems, forming a complete olfactometer setup.
