Is there a contamination risk for my sample when using ambered DURAN® glass?

No, that is very unlikely. In contrast to the usual way of ambering, putting metal oxides into the molten glass in the furnace, DURAN uses a different approach. DURAN® glass is ambered by a post-processing Stepp only on the outside of the vessel. The inner surface remains unchanged.
