In 1948, Hermann Költgen founded the company with a starting capital of 1,000 DM, borrowed from his mother. Today, 75 years later, DIATEST is a globally networked company that successfully competes in the market.

Looking back over such a long period of time, we noticed the developments the company has gone through in these almost eight decades. Again and again, the most modern machines of those times were used. DIATEST was always on the move, entering new markets all over the world and developing new solutions and products.

75 years of DIATEST - and we can only show a small excerpt. There is so much more lying dormant in our archives and databases. But just take a look for yourself and travel with us through the history of the company.
