Vials, Septa

For sealing of snap ring vials.

The short thread vials ND9 SureStop™ 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.

• Stopper ring as protection against over-tightening
• 1st hydrolytic class glass
• In clear and amber glass
• Wide opening requires matching micro-inserts

* With alphanumeric coding on the edge and the bottom of each cavity. Suitable for storage in the fridge. Temperature stable between -80 °C and 100 °C.

2in1 KITs contain 100 vials (1.5 ml) and 100 closures in an orange PP-Box. As both components are always required at the same time, 2in1 KITs are a convenient way to obtain and store all required items for analysis. All advantages of the individual components (cleanroom packaging of the vials, recloseability of the packaging, etc.) remain unchanged.

Any other combination of vial and seal as a 2in1 KIT available.

As an alternative to snap ring seals, snap ring vials and micro-vials ND11 can also be sealed with crimp seals ND11 since the two snap ring lips have the same height as a crimp neck.

Crimp seals ND11 with aluminium septa
Septa made from aluminium are suitable for storing standards or reactive substances that can attack normal septum materials. There is also no risk of contamination of the samples with plasticisers, silicone or butyl rubbers or by PTFE, FEP or TEF components. A ring placed above the aluminium septum achieves an excellent seal on the stopper system.
