[Translate to English:] Zwei Personen sitzen an einem Tisch und unterhalten sich. Vor ihnen liegen kleine metallische Teile.

[Translate to English:] Eine lächelnde Frau in einem Laborkittel steht an einem Mikroskop und wirkt freundlich und professionell.

[Translate to English:] Eine Forscherin arbeitet an einem wissenschaftlichen Experiment in einem Labor. Sie beugt sich über ein hochentwickeltes Gerät, das Teil einer Apparatur zur Materialanalyse oder einer ähnlichen Untersuchung ist. Der Fokus liegt auf der präzisen Handhabung und Überwachung der technischen Ausrüstung.

Together with its MPA Bremen division, Leibniz-IWT offers targeted support to industrial companies, experts, insurance companies, and private individuals. At the institute, we have the expertise and equipment needed to conduct a wide range of tests and characterize samples from the fields of metallic materials, construction, and microbial corrosion. Our scientific and technical colleagues are happy to assist you with services in the areas of damage analysis, certification, and materials testing, as well as contract work in materials manufacturing and processing.

Why you should contact us:
We can provide you with the services and contact persons you need to help you. With our scientific expertise and many years of experience, we are your point of contact for measurement, testing, production, and simulation—especially in the field of metallic structural materials, building materials, and microbially induced material attack.
