This Sanyo MCO-18AIC(UV) Double-Stacked Incusafe Air-Jacketed IR CO2 Incubator is in great condition, has been tested and is guaranteed to be functional. This item came from a local lab that upgraded equipment and was in use prior to removal. We urge customers to view all photos as they show overall condition, included accessories and functionality. We will be happy to provide additional photos or information so please feel free to contact us with any questions. PLEASE NOTE: Both incubators were successfully tested to a setpoint of 37 degrees Celsius (please see last two photos). The top incubator has a functional UV lamp (photo #10), while the bottom unfortunately does not. The lamp itself is fairly inexpensive and can be easily obtained online. This minor issue is reflected in the list price.
