Construction of a Dual Vapour and Liquid Managment Still Head


To build this type of still head you actually only need 2 valves rather than the 8 I used. I did it because I like "CONTROL" and the idea of symetry. This unit should allows me to experiment a bit with all variables. Remove the valves that are crossed out
and re-jig the plumbing so that the water runs from one condenser to the other. The only other controls you need are a needle valve for liquid management and a 1" gate valve for vapour management, the ones with the green tick. You can control the water at the tap.
You might replace the Vapour side condenser with a small Liebig codenser as it doesn't have to handle much heat at all. About 10% of your input power.....maybe 80watts or a light bulbs worth of power.
