Stündenglass Gravity Bongs | Rotating Glass Infusers

Frequently Asked Questions

• What is a Stündenglass?

  The Stündenglass is a gravity-powered, 360-degree rotating glass infuser. By flipping the device, water displacement and opposing airflow pull smoke through the infusion chamber without any inhaling required from the user. It delivers the smoothest, densest hits of any gravity-based smoking device, and has become the premium standard for the category since its launch.

• What's the difference between the Stündenglass Gravity Infuser and the Kompact?

  The original Stündenglass Gravity Infuser is the full-size 2-liter capacity flagship. The Kompact is a smaller, more travel-friendly version with the same rotating gravity technology in a reduced footprint. Both produce contactless draws and accept the same Modül system attachments for dry herb and concentrate use.

• How do you use a Stündenglass?

  Fill both glass globes with water to the recommended line, load the bowl with your material, light it, and then slowly flip the device 180 degrees. The rotation pulls smoke through the infusion chamber and into the lower globe. Flip it back to push the smoke up to the mouthpiece for inhalation. The entire process is contactless — you never put your mouth on the device until the draw is ready.

• What can I use with a Stündenglass besides dry herb?

  The base Stündenglass works with dry herb, concentrates, and traditional hookah or shisha. With the Modül attachment, it converts to a desktop dry herb vaporizer using convection heating. The Modül + Dok bundles add concentrate functionality. The Beverage Cloche accessory lets you use the Stündenglass for aromatic mixology and infused cocktails as well.

• What is the Stündenglass Modül system?

  The Modül is Stündenglass's attachment system that converts the gravity infuser into a desktop dry herb vaporizer. It uses convection heating instead of combustion, producing clean vapor while still benefiting from the rotating gravity airflow. The Modül + Dok bundles extend the system to concentrate use, making the Stündenglass one of the most versatile devices in its category.

• How do I clean my Stündenglass?

  Disassemble the glass globes, infusion chamber, and tubing. Rinse all components with warm water immediately after use to prevent buildup. For deeper cleaning, soak the glass parts in isopropyl alcohol (91% or higher) plus coarse salt, then rinse thoroughly. Avoid getting moisture into the aluminum housing. Clean after every few sessions to maintain performance and visual clarity.

• Does Stündenglass come with a warranty?

  Yes. Stündenglass offers a manufacturer warranty on all devices, with a 10-year extended warranty available for registration. As an authorized Stündenglass dealer, Discreet Smoker honors the full manufacturer warranty on every device sold, with original packaging and registration materials intact.
