This Millipore Milliplex Multiplexing System is in good condition and was removed from a working environment. This unit came from a local lab that had surplus equipment. Software required for operation is not included (reflected in list price). As a result, this listing is being sold for "parts or not working condition". We urge customers to 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.
