The GRAV Medium Upright Bubbler operates as a tabletop glass apparatus tailored for users consuming dry botanicals and botanical extracts. Designed by Stephan Peirce, this compact unit bridges the gap between larger filtration devices and manageable hand-held pieces. It is constructed from high-grade borosilicate glass, ensuring thermal resistance and structural reliability for daily usage. The bubbler provides consistent vapor cooling while maintaining a relatively small physical footprint, making it suitable for both novice and experienced users. Its minimalist structural aesthetic requires straightforward maintenance and integrates seamlessly into regular botanical sessions, offering functionality without excessive complexity.
Fixed Fission Downstem
This glass piece incorporates a fixed downstem equipped with a three-hole fission diffuser. The internal design effectively fragments the vapor as it enters the water chamber, providing consistent cooling and filtration during each draw. By fusing the downstem directly into the bubbler body, the structure mitigates the risk of accidental internal breakage. For optimal draw resistance, a water level of approximately two inches is recommended.
Angled Ergonomic Mouthpiece
The neck of the bubbler features a 45-degree angle, allowing users to draw vapor comfortably from a seated position. This specific positioning acts as a natural splashguard mechanism, effectively preventing liquid from traveling upward into the user’s mouth. Furthermore, the mouthpiece is finished with a flat, thick glass lip wrap that provides a comfortable contact point during inhalation.
Thick Flared Base
To ensure a stable tabletop experience, the bubbler is anchored by a 4.625-inch wide-flared base. This broad foundation significantly lowers the center of gravity, minimizing the likelihood of the unit tipping over during routine use. The structural weight of the 44mm glass tubing combined with the solid base provides a reliable resting stance between sessions, enhancing overall stability and durability.
Dual Compatibility Design
Out of the box, the piece is equipped with a 14mm female joint configured at a 90-degree angle and includes a standard cup bowl for dry botanical use. However, the standardized joint size allows users to effortlessly transition to botanical extracts. By swapping the included bowl for a 14mm 90-degree male attachment, the bubbler transforms into a fully functional extract setup.
