Abstract

The glass container stores and preserves pharmaceutical or diagnostic solutions for medicinal purposes. So that the container is free of silicones and other residues, it is provided with an amorphous, transparent anti-adherent coating (4) over its entire interior surface from its bottom over the wall (3) to the closure device (2). This anti-adherent coating (4) is free of heavy metals, free of silicones, is stable after autoclaving at about 120° C. for about 20 min or hot air sterilization for 30 min at 300° C., has a contact angle for wetting with water of ≧80°, contains silicon, oxygen, carbon, fluorine and hydrogen and is deposited by a PECVD method, especially a PICVD method. If the coating contains less than 0.1% by weight fluorine, then it contains greater than or equal to 10% by weight carbon, but if it contains greater than or equal to 0.1% fluorine then it contains greater than or equal to 5% by weight carbon.
