A Phazon Nutrient Vat is a processing vat featured in Metroid Prime in Elite Control, a research room in Level Two of the Phazon Mines. It is a large cylindrical, closed cask of Phazon, some of which can be seen through a transparent pane on the side of the vat. In the middle of this is what appears to be an interface panel, resembling those found on computer screens. On either side of this are lights that spin around the vat at regular intervals. It is identified in its scan, which implies that it is processing a ration of Elite Nutrient Mix. There are two of these in the room, in opposite corners on the lowest floor.
