Duke River Center Facilities and Equipment

The River Center analytical laboratory has the capacity to analyze water and trace gas samples.   The lab is equipped with a high purity DI system (Barnstead Genpure xCAD UV), glassware washing room (acid bath and Miele G7883 washer), large drying oven (5 c.f. Fisher Scientific Isotemp gravity-flow oven), large muffle furnace (1.6 c.f. Thermo Scientific Thermolyne single-setpoint tabletop furnace) balances (Mettler Toledo MS NewClassic and Denver Instruments S-2002) and cold storage room.
