Limited Warranty

Au(111) thin film is a very delicate product with a limited shelf life. If the customer is not satisfied with the quality of the product at reception, we offer a replacement possibility on a one to one basis if the films are returned to Phasis and declared defective. This warranty no longer extend if the customer touch, anneal, cut, or treat in any way the gold surface potentially leading to a degradation of its surface. The warranty also falls if the samples have been kept outside their box for a long time and if the samples are older than their shelf life.
