Schott presents new, innovative screw caps for Duran laboratory bottles.
The universally applicable 'Premium Cap' meets the highest demands for storing and packaging products from pharmaceutical, chemical and food industries.
In order to prevent any form of contamination, these caps do not contain any colorants or plastic pigments.
The welded-in silicon seal is coated with PTFE on both sides for highest demands on chemical resistance.
The welding prevents the medium to leak into the space between the lid and the seal and remains extremely tight even after having been opened and closed several times.
The 'Premium Cap' is characterised by a temperature resistance from -196C to +260C and complies with USP/EP and FDA standards.
