to the 3/4" bung on the lid.
Use a 2" PVC threaded adapter to add a T with 2x ball valves, one with a 3/4" barb, the other with an air hose quick connect (male)

Using a compressor, we can now move ethanol from one vessel to the other by applying positive air pressure to the head space of the barrels.
Could we get a picture of what you are trying to mean? I assume that we should have a T on the bottom with 2 valves, and one of them is also a quick connect for the compressor. So would this mean we would have 2 quick connects, one on top the other on the bottom?
What degree of mixing do you all do when your solvent is under -67°C? I’m going to be going with 2 washes each for 5 minutes. On the flip side, is there such thing as too much stirring? Merry Christmas everyone!
