Our service for you

Do you have questions about our products? Do you want to know which other services we offer? Are you looking for material properties?
Here you will find information and details about plastics and glass products
such as chemical resistance or temperature specifications.
Our FAQs will certainly answer many of your questions!

Repairs
We will gladly carry out repairs on your defective devices. However, the defective items should be clean, sterilized and, if necessary, decontaminated. The repair should also be worthwhile in economic respects.

As we care about the safety of our employees and we are acting responsibly, we reserve the right to demand a certificate of decontamination (clearance certificate).
