Supporting our customers at every stage in the development process

To make a product work, you need more than ideas and prototypes. You’ll need to make sure it passes specific properties and certain tests. These characteristics originate from both material choice and processing. So, for either development or quality control, you’ll need to identify and quantify these properties. To do so we have an entire analytical service designed to help you achieve that. At the moment our analytical service has following tests with their specific protocols in house but when needed, we design specific tests or reach out to fellow institutes/colleges that can do the test for you.

We use our analytical lab test to discover characteristics or the chemical makeup of the tested sample. Mainly used to do reverse engineering for industries such as pharmaceuticals, food, electronics and plastics, but also highly fitted for failure analysis or identifying contaminants or stains on products. Where work accordingly ISO standards.

With our in-house expertise and machinery, we can offer a wide range of testing services, which we divided in 5 different categories: Physical, Mechanical, Thermal, Optical and Rheological.
