This Bellco 7785-D1008 Bell-Ennium 1 Position Digital Magnetic Stirrer has been tested and is guaranteed to be fully functional. This item came from a local lab that had surplus inventory. Stirrer shows slight aesthetic signs of normal use. The only minor issue worth noting is the digital display is slightly dim. We urge customers to view all photos as they show overall condition, included accessories and functionality. Please feel free to contact us with any questions.
