Copper Bubble Plate

Can be fitted inside a 2 inch Sight Glass. 

How it works:

Vapour that comes into contact with the plates and caps condense back into a liquid. Some liquid drips back down through the column but is eventually forced back up though the caps and plates. This process creates an end product that has essentially been distilled multiple times in a single run, which results in a higher proof when compared to an empty column.
