San Diego Instruments Gemini II Rodent Active and Passive Avoidance Testing System

The San Diego Instruments Gemini II Avoidance System is a specialized rodent behavioral testing apparatus designed for active and passive avoidance paradigms in neuroscience and behavioral research. It supports testing in both rats and mice, with a quick configuration switch to accommodate different species. Engineered with 16 infrared photobeams per enclosure, it enables precise tracking of subject movements and responses. The system delivers customizable auditory stimuli alongside cue lights and non-heating LED house lights, ensuring versatile test conditions without thermal interference.

Key system features include:

• Support for up to 8 independent testing stations, ideal for high-throughput behavioral screening.
• Compact enclosures constructed from acrylic and aluminum, with stainless steel gates for durability.
• Exterior dimensions of 26" (W) x 13" (D) x 17.25" (H) with an interior space of 9.5" x 8" x 8" per test side, accommodating standard laboratory rodents.
• Connectivity via a standard 16-foot cable enabling flexible integration with data acquisition systems.
• CE Certification, meeting safety and quality standards for laboratory instrumentation.

This system is essential for researchers focused on neurobehavioral studies, learning and memory assays, and biomedical engineering applications involving rodent models. Its design supports biotechnology workflows by enabling behavioral phenotyping critical in gene editing, molecular diagnostics, and bioprocessing research. Despite this unit being sold as salvage with a damaged connection port and requiring a replacement power button, its core components remain highly valuable for system repair or internal parts replacement.

The Gemini II system is widely used for behavioral neuroscience, pharmacology, and synthetic biology research where precise measurement of avoidance responses is critical. It is a reliable platform for laboratories prioritizing live-animal behavioral analysis and translational research in molecular biology and biotechnology domains.
