This Daavlin UV Research Unit Irradiator with (12) 48" x 305/350 UVB Lamps came from a local manufacturer that had surplus equipment. We urge customers to view all photos as they show overall condition, included accessories and functionality. As seen in photo #22 the curtain has signs of wear and will need to be reattached to base unit. 

Please Note: We are trying to locate a manual for the controllers as they are somewhat difficult to navigate. We were able to activate one set of lamps but are unsure of the process in which it was activated. We are confident all lamps work and will continue to search for a manual. For additional information please see last two photos of listing. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions.
