Now under Grenco Science's umbrella, the brand has expanded its reach globally while maintaining its commitment to precision engineering and premium materials.The current product line includes the flagship Gravity Infuser, the portable Kompact model, and the innovative Modül heating system. Each device features aircraft-grade anodized aluminum construction with borosilicate glass globes, backed by a 10-year warranty. The brand has cultivated an impressive collaboration portfolio with celebrities including Wiz Khalifa, B-Real, Mike Tyson, Berner (Cookies), and the Grateful Dead, creating limited-edition pieces that blend functionality with collectible artistry.Beyond cannabis consumption, Stündenglass has pioneered applications in culinary arts, mixology, and aromatherapy, with professional chefs using their devices to infuse foods and beverages with smoky flavors.

Stündenglass began in 2012 as a passion project by Tracey Huston, a former Apple senior technical specialist who applied his engineering expertise to reimagine the traditional gravity bong experience. What started as Huston's personal quest to create the perfect gravity bong remained largely under the radar until 2018, when a family friend gifted a prototype to Seth Rogen. The celebrity's viral video showing himself using the device—and bursting into a coughing fit after just one hit—catapulted Stündenglass into the spotlight and orders came flying in within hours.The brand's trajectory accelerated dramatically when Grenco Science (makers of G Pen) acquired Stündenglass in April 2020 for under $1 million. This acquisition positioned Stündenglass within one of the industry's largest product portfolios while maintaining its innovative edge. Since then, the brand has evolved from a garage operation to a globally recognized leader in gravity-powered infusion technology, consistently pushing boundaries in both cannabis consumption and culinary applications.
