This New Brunswick Scientific G-25 G25 Environmental Incubator Shaker M1024-1000 is in used condition, has been tested and is guaranteed to be fully functional. This item came from a local lab that had surplus equipment. Unit shows some signs of use including a dial knob partially broken (still functional) and the shaker indicator light does not turn on (shaker works fine). Both of these issues do not affect functionality but are worth noting. We also 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/videos so please feel free to contact us with any questions.
