This is a modular for your Alchemist if you want to see the process happening. If you want to watch what is happening. Or you can put plant matter in there and do a distillation. Comes with mesh. Borosillic glass. Comes with two caps so you can put your plant matter in there and freeze it, or leave it in there to make a tincture. Or you can just add this on to your still and treat as a regular modular/ extension to the Alchemist.
