Vials, Septa
Short thread vials and micro-vials ND9, SureStop
The short thread vials ND9 SureStop are available in clear and amber first hydrolytic class glass and are the best available on the market in terms of seal tightness and reliability. The vials have an additional stopper ring at the end of the thread which clearly marks the end point in the screwing-in process. This ensures that the tightness of the seal is independent of the touch or feel of the user screwing the stopper in. This ensures the lowest possible number of standard deviations and high reproducibility of analysis results....

With silicone / PTFE septa
Precision thread screw seals ND18 are made of metal and supplied with fitted septa made of a variety of materials. The hole size is selected so that the cap is suitable both for SPME and headspace applications. However, enough surface is left for the magnet to be able to transport a completely filled vial. The screw-on mechanism ensures that the cap always has a flat surface so that the bottle cannot fall from the magnet. Separation of the vial and cap for disposal after analysis is much easier than with crimp caps....
