Wafer Semiconductor Processing Automated Heating Cooling Unit Durex Hot Plate PN#- 18293 We obtained this unit from a govt. laboratory that sells off their items as surplus. This unit will need some work to be up and fully functioning. We will guarantee the Durex plates work or your money back. But if you want to use the entire unit, you will most likely need to do some refurbishing to make it crank-out wafers. This would ideally be a great parts unit, if you already run some of these in your factory. The chilling plate does come with a lid. We may have other parts for the system, please ask if interested. FREE USA SHIPPING on the heavy thing. Will ship international. Contact me for a price.
