So as Dr. T showed in our earlier posts – we are using a distillation kit from Amazon to get us started.
The only problem is that the kit is supposed to be cooled from water running from a tap, through the Graham condenser, and down the drain. My not wanting to waste water aside, I don’t have a sink in my shop. So we rigged up a heat sink suitable for the same tubing running into and out of the Graham condenser, and added a thermos to act as an ice bath.
A small pump cycles the water from the ice bath, through the Graham condenser, through the heat sink, and then back into the ice bath. We add a few ice cubes to the bath to get it started and then let things cool from there. To that we added a
Peltier Thermo-Electric cooling module from Adafruit. That keeps pumping heat out of the system. We just grabbed the tubing from the hardware store.
Here’s video of Dr. T talking us through the setup we ended up using.
