The Y-Tube Olfactometer for Large Claw-Legged Insects with SS Mesh is a precision laboratory instrument developed for entomological research involving large insects with strong gripping or clawed legs, such as beetles and other crawling species. Standard smooth glass surfaces can limit movement and affect behavioral accuracy. This model overcomes that limitation by incorporating an internal stainless steel (SS) mesh, which provides a textured walking surface and significantly enhances insect mobility and response reliability.

The Y-shaped design allows insects to be introduced through the central stem and choose between two arms carrying different odor stimuli. This dual-choice system is widely used to evaluate attraction, repellency, and olfactory preference under controlled airflow conditions.

Constructed 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 consistent 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 enables 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.
