General description

This magnetic screw cap has been developed for the CTC instrument. The vial has a precision thread with numberous threads to force the septa against the vial to seal it to be gas tight. The center hole is designed to be used for SPME as well as standard Headspace analysis, but still offers enough surface for the magnet to transport a completely filled vial.
