Falling film evaporator systems, devices, and methods are disclosed in the present application. In some embodiments, the falling film evaporator system can include a hollow cylindrical glass tube configured to enclose the major parts of the falling film evaporator system. Furthermore, in some embodiments, inserted into the cylindrical glass tube is another hollow evaporator tube with a dispensing bowl at the top, a reservoir of the dispending bowl facing the inside top of the cylindrical glass tube. Inserted into the hollow evaporator tube is a heating element configured to heat the hollow evaporator tube such that an outside surface of the evaporator tube is heated. At the top of the hollow cylindrical glass is an inlet where liquid flows into the dispensing bowl, spilling over the edges of the bowl, generating a thin film of liquid that is evaporated as it falls down the outside surface of the evaporator tube.

Examples of a device for gettering and surface conditioning are disclosed. The device comprises an elongated tube with a closed first end, a second end and a body extending between the first end and the second end. The body defines an inner cavity of the tube in which a heating device is inserted. The tube is inserted into a vessel so that the first end is positioned within the vessel. A solid metal is mounted closely to the tube in a region surrounding the heating device and a meshed screen is mounted over the solid metal and secured to the tube. When the heating device is on, the heat transfers through the tube's wall into the solid metal melting and vaporizing it, so that the metal vapors travel and coat onto vessel's surfaces. The device can also be used in producing metal alloys such as lead lithium alloys.
