This Thermo Ultra-Low -86C Upright Freezer is in good condition, has been tested and is guaranteed to be fully functional. This unit came from a large pharmaceutical company that had surplus equipment and was in use prior to removal. Please view all photos as they show overall condition, included accessories and functionality. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions. Please Note: Last three photos show unit successfully reaching -85C. We are confident the unit can reach -86C with further testing time. Also note the missing plastic panel as seen in photos #3 and 4. One last issue worth noting is the door gasket is slightly loose in the top corners. The gasket is still functional but may need to be reattached in the loose areas for a perfect seal. We will attempt to repair prior to shipping.
