As our newest base, the Percolator Beaker Base is a great new addition to the Prism Beaker Base family. Inside the beaker lives a cone shaped percolator giving your classic beaker that extra filtration that you’ve always wanted. Pair with any of the Prism tall mouthpieces and you’ve just built yourself a classic beaker set up, but with a little extra filtration. Lastly, it comes with a clear 18mm bowl. However, we highly suggest you check out the colored bowls. It definitely adds that cool pop of color.
