Testing Services Brochure

Analytical Laboratory Services

We specialise primarily on polymer-related analyses of, among others, PET, PBT, PLA, PA, PE, PP, PPS and PEEK. We offer comprehensive analytical services from the monomers via the intermediates and polymers to the resulting final products and side-products. We design test programmes specifically for questions in relation to these areas, conduct the analyses and provide a verified interpretation of the results.

This list is not exhaustive, and  we offer a large number of additional analyses and tests. We conduct our analyses according to recognised industry-wide standards, or, where these do not exist in relation to the test we have been asked to undertake, we use our validated in-house testing regulations. We are happy to provide a detailed breakdown of costs and an estimated timeframe along with details of the sample quantity required for the test.

If you can’t find the test you need in the list above, get in touch with us.

We look forward to finding a solution to meet your needs.
