General description

These vials require a special cap with an 18 mm thread. The standard 18-400 threaded caps will not fit this vial. The part numbers for caps that are available for these vials are SU860101(with PTFE/silicone, 1.3 mm thick), SU860102 (with PTFE/butyl, 1.6 mm thick), and SU860103 (with PTFE/silicone, 1.5 mm thick). These caps are made from stainless steel and are magnetic.


Headspace vial may be used for the following:
  • In the determination of partition coefficient of ethyl acetate in water at 0° C from independent analyses of the total amount of ethyl acetate present in the vial, by automatic equilibrium headspace gas chromatography and vapor phase calibration (VPC).
  • It may be used in the analysis of volatile polar residual solvents present in pharmaceutical products, during development and optimisation of headspace SPME method by GC-MS.
  • It may also be used in the isotopic analysis of 18O in the leaf water of C3 and C4 grasses, during establishing a grassland signature in veins, as it was found that grasses with different photosynthetic pathway have different interveinal differences.
  • It may also find application, in investigating metabolism by Pseudomonas fluorescens of volatile haloaliphatic hydrocarbons like 1,2-dichloroethane and 1,2-dichloropropane, which are some of the major contaminants of underground aquifers.
