There­fore, it is these areas that require special atten­tion and servicing. After numerous years of expe­ri­ence in this industry sector, the two co-founders of the Tentamus Group set out to concen­trate on exactly those prod­ucts – those that we cannot do without in our daily lives. Capable of influ­encing us for better or worse, these prod­ucts repre­sent the most inti­mate contact to our daily lives; namely agri­cul­ture, food, phar­ma­ceu­ti­cals and medical products.

Global Network – Local Approach

Today, Tentamus offers a global network of highly special­ized labo­ra­to­ries, all of which are equipped to ensure the quality and safety of the tested goods. To main­tain this, Tentamus is active in product- and industry-specific knowl­edge centres, unifying the skills and know-how from each industry, which thereby enables us to provide our clients with the customer-oriented services through our global network.

Labs for Life

As a tech­nology leader in the life sciences industry, Tentamus dedi­cates itself to the contin­uous advance­ment and renewal of its analytic methods and devices. Tentamus’ dedi­ca­tion to progress allows us to bring our clients the highest degree of quality and safety and thus, contribute towards the centuries-old need for safe food and medical products.

Our Vision Tentamus


Our ambi­tion is no less than to become the most acclaimed company in the world for safety and quality assur­ance. The Tentamus Group has set itself the goal of becoming the best-known global labo­ra­tory service provider while still supporting its customers locally.

Our moti­va­tion to achieve our vision is the satis­fac­tion of our customers!

tentamus about us mission


Tentamus aims to offer its clients on-site services with which they can verify the safety and quality of their prod­ucts in the shortest time possible.

We will under­take the neces­sary efforts for that in various special­ized labo­ra­to­ries in the life science sector. Each of our labo­ra­to­ries is a fron­trunner in its field. To accom­mo­date the increas­ingly complex demands of our customers, we have inte­grated our labs into a global network. In this way, we’re able to offer global solu­tions with local points of contact.

Together, the breadth of our expe­ri­ence and the use of cutting-edge scien­tific methods and lab equip­ment allow us to do what we do best: Ensuring the quality and safety of our clients’ prod­ucts and services. We unite manage­ment and scientific-expertise.

The Tentamus Group is like a global family that is char­ac­ter­ized by dili­gence, preci­sion and diver­sity. There is trust and trans­parency within this group and towards our part­ners and customers. The satis­fac­tion of our customers and employees is our greatest asset.
