These vials provide the advantage of a sealed ampule with the flexibility of a screw cap bottle or a septum vial. These unique, screw-cap sample containers with a 1.2 x 28mm height capillary opening are designed for the storage of volatile samples and reference standards.

Advantages:

• No appreciable change in concentration -even when open
• Secure storage, minimal evaporation
• Minimizes contamination risk
• Sample filling and removal using a standard GC syringe
• Essentially spill proof
• PTFE-lined screw-cap

Applications:

• Storage of liquids removed from conventional glass ampules
• Storage of stock and standard solutions
• Storage of difficult samples such as volatile halogen compounds or BTEX aromatics
• Archiving of production or QC samples and extracts
• To extract a solution from CERTAN® capillary vials use a syringe with a needle diameter of 0.8mm or smaller and a minimum 70mm length
