GRAV Gravitron (Medium) – The Legend of Gravity in Clean Glass Design

Anyone who loves classic gravity smoking cannot ignore this milestone. The GRAV Gravitron® was the world's first gravity pipe made entirely of high-quality glass – and it continues to set the absolute gold standard to this day. Forget unhealthy plastic bottle constructions from old times; the Gravitron brings pure physics, maximum efficiency, and an unbeatably clean aroma to your table.

In the Medium version, the system offers the perfect balance of a handy size and a tremendous lung volume. An absolute must-have for connoisseurs who want to experience the raw power of gravity in its most elegant form.

Highlights of the GRAV Gravitron (Medium)

• 100% High-Quality Borosilicate Glass: No plastics, no nasty fumes. Both the outer bottle and the inner chamber are made of robust, heat-resistant borosilicate glass for the absolutely purest taste.
• Ingenious Bottle Design Upgrade (Version 2): In the latest generation, the Gravitron features a reinforced glass wall at the bottom and a perfected mouthpiece including a stable rubber grommet that seals the glass bowl bomb-proof and completely airtight.
• The Principle of Pure Physics: By slowly raising the inner bottle, a massive negative pressure is created in the vacuum. This gently draws the smoke into the chamber without any material loss. When pressing down, gravity pushes the dense, cooled smoke upwards with constant pressure.
• Extremely Efficient & Economical: The system inhales for you. Since no smoke escapes unused into the room, you get the absolute maximum effect and density from a minimal amount of herbs.

Pro Tip for the Perfect Session

The Secret to the Draw Technique: Pull the inner bottle up very slowly and evenly while holding the flame to the bowl. The slower you pull, the denser and creamier the smoke in the chamber will be. When you remove the bowl, relax your lips over the mouthpiece and let the bottle slide into the water under its own weight – physics does the rest for you, without any strenuous pulling!

FAQ – Frequently Asked Questions

1. How much water do I need for the Gravitron?

Fill the outer glass base with cold water until the inner bottle is almost submerged up to its neck when fully pushed down. Make sure no water splashes out at the top when pulling up.

2. Can I also use the Gravitron Medium with a vaporizer?

Yes, absolutely brilliant even! Thanks to the standardized 14.5mm female joint on the mouthpiece, you can simply swap the included bowl for a suitable water pipe adapter (WPA) of your vaporizer (e.g., Dynavap, PAX, or Tinymight). The Gravitron's negative pressure draws the vapor perfectly and evenly from the heating chamber.

3. What's the best way to clean the system?

Since the Gravitron consists of two simple, smooth glass cylinders without complicated percolators, cleaning is a breeze. Simply separate the bottles, rinse with warm water, and for stubborn resin residues, use some isopropyl alcohol (ISO) and coarse salt. Shake once, rinse – done.

4. Is the Gravitron Medium stable?

Yes. Thanks to the thick glass wall and the wide, flat base of the outer section, the system stands very stable on a coffee table. However, it is still glass, so a firm, level surface is essential during use.
