This Beckman Coulter Ac•T diff Analyzer is in good condition and was removed from a working environment. This unit came from a local lab that had surplus equipment and was in use prior to removal. As seen in photo #3 this unit will require maintenance prior to operation. As a result, this unit is being sold as-is. We urge customers to view all photos as they show overall condition, included accessories and useful information. Listing only includes what is shown in photos and does not include any additional accessories. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions.
