Large Gravitron®

The GRAV Large Gravitron uses gravity and water displacement to create thick, milky smoke through its upgraded borosilicate glass construction, which is five times thicker than previous versions. This closed-system design features a platinum-cured silicone grommet at the base contact point, a GRAV 19mm Funnel Bowl that accepts standard male fittings, and a neck flange for easy handling during operation. The straight-sided chamber design allows for efficient cleaning, while the gravity mechanism eliminates the need for manual draw effort.
