Safety first

In addition to exacting quality and design standards, we are also committed to product safety, a topic which is constantly gaining in significance.


We consistently ensure that the current standards and statutory stipulations are adhered to exactly. Furthermore, all products are regularly tested in an independent laboratory to ensure that they are safe within the meaning of the Food Contact Material and Consumer Products Ordinance.

Permanent quality control and monitoring

In a digitalised glass control process, each individual vacuum-stable glass is tested for heat retention and stability.


Certification of our complete plastics production in accordance with TÜV DIN ISO 9001 guarantees the flawless manufacturing of the vacuum jugs blanks.


In addition, all sub-suppliers are obliged to adhere strictly to the respective legal stipulations.
