We are an accredited testing laboratory in accordance with iso 17025. Testing is conducted according to international standards and in compliance with your customers’ requirements. We work with you to develop our testing procedures and adapt to your needs and wishes.

We perform testing through the entire life–cycle of your sample — from raw material to material, half–product, or product and waste. On the basis of acquired testing results we offer expert counselling to help you optimise your processes and sales.

Regular periodic testing of samples reduces your risk of complaints. This allows you to:
  • keep your customers happy;
  • maintain your company’s good reputation;
  • improve cost–effectiveness.

In the case of complaints we join forces and find an appropriate solution to optimise your processes or identify irregularities of supplied goods.
