Say hello to the Percolator Beaker Base, one of the smoothest bases in the Prism Classic base collection! Inside this beaker, you’ll find a cone-shaped percolator that adds a whole new level of filtration to your Prism Classic setup. Pair it with any of the Prism tall mouthpieces, and you've created a classic beaker setup with that extra filtration boost.
