Barnes Maze


Ideal for testing spatial learning and memory, the Barnes Maze motivates animals to hide from the bright, open platform by finding the small, dark “escape box.” Animals learn the escape box’s location without the stress of swimming or food deprivation and false escape boxes remove the possibility of inadvertent cues. San Diego Instruments (SDI) designed its Barnes maze to be easy to use, clean and transport. With a variety of color options, SDI’s Barnes maze adjusts to fit a wide range of experiments. Backed by a one-year warranty and our first-rate customer service, purchasing a Barnes maze from SDI guarantees you an exemplary product and ongoing support.
