A plurality of disc-shaped substrates carry light emitters and are axially stacked, spaced apart, in a metal housing to dissipate the heat produced by the light emitters. The housing comprises mutually connected elongate planar ribs that abut the light emitters or substrates for thermally connecting the light emitters to the housing. The ribs have shoulders. The substrates are received between the ribs and abut the shoulders. The shoulders are positioned proximate each light emitter in intimate contact with the substrate for efficient heat dissipation.

A mixing vessel contains a septum, dividing a first chamber from a second chamber. By relatively moving the septum with respect to the ends of the vessel, and flowing a fluid through the septum, the fluid is treated as it moves from the first chamber to the second chamber. The particular configuration of the septum allows for treatments such as mixing, reacting, heating, and cooling, as well as filtering of the fluid.
