Is it a rotary union or some other magical device. Also how does steam transport occur between the two flasks. I only ask as I am contemplating building one myself.

The capacity of the base is about 3-3.5 liters (for legal reasons I can’t make it much bigger). With this setup I can do the full 3 liters as opposed to my current 3 liter setup because the lid will give me headroom. Also, I am adding a second peristalitic pump that can pump product out of the base so I can operate continuously without breaking down the machine.
