The 4F-MC-W-404040 insect rearing cage is designed for precision insect handling and observation in research settings. Measuring 40 x 40 x 40 cm, it features fine white mesh on all sides, ensuring excellent airflow while preventing the escape of tiny insects like mosquitoes or whiteflies. One side panel includes a clear plastic window, allowing researchers to monitor insect behavior without disturbance. The cage is equipped with a double-sleeve opening on the front panel, enabling safe, contamination-free access for feeding, cleaning, or sample collection—ideal for use by multiple researchers. Its lightweight yet sturdy design makes it easy to move between lab benches or field sites. The 4F-MC-W-404040 cage is suitable for insect colony maintenance, behavior studies, and small-scale bioassays. It is especially useful in settings where visibility, airflow, and operator safety are critical. This model supports efficient and hygienic handling in entomology labs and controlled environment rooms.
