For sale is a Barnstead Thermolyne Model No.D11931 "NANOpure - Diamond" Water Filtration System. From the OEM website: "Produce 18.2 megohm-cm water quietly while maintaining a small laboratory footprint. A 0.2m absolute final filter assures water is bacteria- and particle-free. Volumetric dispensing eliminates overflow accidents when filling carboys. Standby mode maintains water purity during periods of non-use, and an automatic sanitization cycle keeps the system clean." Operates on 1/60/115V AC power, 100 Watts. All of the items pictured are included with this sale. I removed this unit from a true clean-room, laboratory environment. It was in use prior to removal.
