One or two small things that I find useful you may wish to add to
When the column is being balanced, the flow of cooling water is much
easier to control if you use a needle valve, and be sure to install
it at the VERY END of the pipe system where the water runs to waste.
This means that adjustments have an immediate effect, and the flow
changes are instantly visible.
On my EL I noticed that the temperature at the vent hole on top
hovers 2 or 3 degrees either side of 50C when the column is
balanced. I did NOT measure down the hole but, with a probe tip
sitting loosely IN the hole. This may prove to be a useful
indication that you are not loosing product to the air.
