Mounted to the Scale-Up Series™ stand via the 12841 vertical rod assembly, the pressure relief manifold inlet/outlet set will help protect the glass vessel from breakage due to an excessive pressure differential exerted by the thermal transfer fluid while the vessel is isolated or disconnected from the circulator. Available as a set, individual inlet or outlet and sized with either a M16x1 or M24x1 union. Operating range -40 thru 232 degrees C.
