Research Applications

  • NokeLab pressure-release vial and cap design integrates a pressure-relief function, ensuring safe operation under the high pressure typically generated during headspace incubation.
  • Thick-wall glass with a pressure-release design withstands internal pressures up to 60 psig, while ordinary vials without these safety features may rupture.
  • UltraClean liners for sensitive analyses, combining the highest purity silicone and PTFE film with an advanced curing and conditioning process.
  • Available with silicone/PTFE or Pharma-fix butyl/PTFE septa, with customizable silicone hardness.
  • Compatible with 6 mL, 10 mL and 20 mL ND20 crimp top headspace vials.

Key Features

  • ND20 crimp caps available in aluminum or magnetic steel, with magnetic caps compatible with magnetic-lifting autosamplers.
