Tube Glassware: Where Chemistry Meets Contemporary Design

Florian Seidl reinvents the drinking glass with modular, stackable elegance.

The Tube glassware series draws direct inspiration from the world of chemistry, channeling the iconic form of test tubes into a sophisticated collection of drinking glasses. Florian Seidl, the designer behind the project, reimagined borosilicate glass—a material renowned for its strength and heat resistance—by creating a double wall structure. This design not only echoes the floating elegance of laboratory glassware but also provides practical benefits, such as insulation and visual intrigue. The transparent outer layer supports an inner tube, creating a striking visual gap that sets the collection apart from conventional tumblers.

Functionality is at the heart of the Tube collection. Each glass features a flat-bottomed, ergonomic design suitable for a variety of beverages, from water and juice to cocktails and beer. The modular approach allows the glasses to be produced in three distinct sizes—200ml, 330ml, and 500ml—each with an identical diameter for easy stacking. This versatility caters to both casual and formal settings, while the dishwasher-safe material ensures convenience in daily use.

Borosilicate glass, the material of choice, is celebrated for its durability, recyclability, and adaptability. The production process enables a range of shapes, thicknesses, and color combinations, allowing for creative presentations and personal expression. The commitment to sustainability extends beyond the product itself, with packaging crafted from recycled cardboard to minimize environmental impact.

The design process involved extensive research into material properties and form, with traditional sketching and 3D modeling guiding the development. One of the primary challenges addressed was achieving modularity and stackability without compromising the visual statement or functional integrity of the glasses. The result is a collection that balances technical innovation with artistic expression, earning the Tube series a Silver A' Design Award in 2025 for its excellence and creativity.

Florian Seidl’s Tube collection stands as a testament to the potential of everyday objects to inspire wonder and elevate daily rituals. By blending scientific inspiration with contemporary aesthetics and sustainable practices, the Tube glassware series invites users to enjoy their favorite drinks in a vessel that is as thoughtful as it is beautiful.

With its award-winning design and commitment to both form and function, the Tube collection offers a fresh perspective on drinkware—one that celebrates the intersection of art, innovation, and responsible design.
