Earlier in the year (before I found this site) I built a reflux still that was simply a 1m long 72mm wide column with a coil dephlagmator and a 12mm liebig coming from the column at the top.
Obviously this didn't work too well so I rebirthed it into a CC which I am running for the first time today. It still has the 72mm column (about 45mm shorter now though) and has 65mm head piece that slip fits over the column. Total length now 1.1m to the bottom of the lyne arm then another 180mm to the take off tube. (A bit short for the width of the tube but we'll see how it goes.) It is sporting a 300mm long 1/4" doble helix condensor. Still needs a bit of clean up on the outside but I just want to make sure that she'll do what I need her to.
I'm running about 45L of 28% so I expect to be here for a while today.
Cheers, Heffers
