3 Inch Copper Bubble Cap Plate

3 Inch Copper Bubble Cap Plate for windowed section plated reflux column. These copper bubble plates are used in a windowed section flute still column positioned between sections to help with separation of alcohol and waters. The alcohol / water bubbles up on the plates allowing the distiller to see the action happening in the still column. More bubble cap plates in a column and a taller column with a reflux condenser or dephleg create a high percentage neutral spirit. Copper bubble plates can be taken apart and cleaned with citric acid or mild acid solution.
