WHEATON® BlueMAG Screw Caps
This polymer-magnetic hybrid cap is designed to address the robustness issues found with either all-metal 16 & 18mm caps for headspace analysis or caps with ferrous ‘metal washers’ atop the cap commonly found in the 9mm size. WHEATON BlueMAG screw caps feature an innovative crimped surface feature which provides both a flat, squared surface with respect to the machine automation magnetic geometry as well as extra ferrous mass to ensure even the largest headspace vial, filled with lead shot, can be confidently and securely transported. These caps also eliminate the ‘glass-to-metal’ grinding and provide added assurance against breakage and confidence of use in automated sample transport systems.
