The Pure Distilling 2" Copper Bubble Plate is designed to be inserted into a 2" sight glass using a specially designed 2" Bubble Plate Seal (sold separately). 

Bubble plates increase separation efficiency during distillation by repeatedly contacting rising vapour with liquid on each plate. Seals to fit are also available for separate purchase.

Please note that we do not recommend using bubble plates with our Pure Distilling Reflux Condenser, or alcoengine unless the user is particularly keen to experiment. These Reflux Condensers are liquid controlled, meaning it already has a pseudo bubble plate working inside the tower.

If anyone is keen to try using a bubble plate in a sight glass, the system will need to be run on the large 1700W element only once the boiler comes up to temperature. The system will enter slow mode very early, and the run will typically take more than 5 hours. Expect plenty of activity in the sight glass during the first hour of the run.

These are better suited for those using vapour-controlled condensers or Pot Condensers.
