The Pot Still Alembic Condenser is best used with the T500 Boiler and the Pot Still Alembic Dome Top. You can use this with the T500 Boiler without the Pot Still Alembic Dome Top, to do this it fits on to the lid of the T500 Boiler. This condenser is what differentiates this still from the T500. It is what retains the flavor rather than stripping it out by refluxing. This comes with a thermometer, tubing and tap adapter set.
