Hint: To extract a solution from CERTAN capillary vials use a syringe with a needle diameter of 0.8 mm or smaller and a minimum 70 mm length.
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 28 mm height capillary opening are designed for the storage of volatile samples and reference standards.
  • 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 spillproof
  • PTFE-lined screw-cap
  • 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 of QC samples and extracts.
