Product information "Epithermal XRF Set large" The set comes in a Pellet case with foam inlay and silica gel capsules. Epithermal deposits form by hydrothermal fluids circulating through fractures and cracks in rocks at depths of < 1500 m below the Earth’s surface. Cooling of these fluids leads to metal deposition in veins.

SCP SCIENCE manufactures supplies and standards for ICP, AA, and XRF analysis plus sample preparation systems including Graphite Block and Microwave Digestion systems. Our Environmental Robotic Analyzers include BOD, COD and TitrEC a pH, EC, Alkalinity Analyzer.
