Our wet chemical laboratory works with a broad spectrum of various methods making the analysis of glass’ important characteristics possible. That is why we are among others capable of identifying the exact composition of glass or parameters appropriate to pharmaceutic standards. In the following structure for each subitem some methods and possibilities are presented. However, they do not depict our full range in this field. Please contact us via the contact formula or call us if you want to find out, weather we can offer a helpful product.
