The GRAV® Hourglass Beaker Recycler is 10" tall and made on 44mm clear tubing with black accents. Its fission downstem diffuses smoke through water and is fixed inside the pipe to prevent damage. Its topmost chamber functions as a bubbler chamber, pulling water up from the beaker to filter the smoke before draining back into the base. The hourglass recycler comes ready to use with a 14mm GRAV® Funnel Bowl and functions best with approximately 1.5" of water.
