99% purity - no exceptions

Choosing the right material is key for production quality. This is why we exclusively use aluminum oxide with a purity of 99% to make our ceramic supports. Compared with products from competitors, particularly polymer membranes, our ceramic membranes stand out due to their high chemical, thermal and mechanical strength, so that we can guarantee a long service life. This is the only way to come up to the demanding requirements of our customers without difficulties.

Quality assurance is not left to chance, neither. We keep reference samples of all lots that have been supplied to us and delivered by us to customers. In this manner we can always find out who supplied us with the relevant material. Most of our suppliers are European or US companies with whom we have entertained business relationships based on mutual trust for many years.
