PerkinElmer* Headspace Crimp-Top Septa and Pre

PerkinElmers patented vial and cap design incorporates pressure relief features which guarantee safe operation with the high pressure typically developed during thermostatting. Ordinary vials and caps without these safety features may burst. Very low background peaks and lowest permeability, includes aluminum caps and star springs. The Butyl Rubber Septas are recommended for repetitive injections from the same vial while the aluminum-coated silicone rubber septa and the PTFE-coated silicone rubber septa are not recommended for repetitive injections from the same vial. The butyl septa is tested to 20 ppb of toluene. Test conditions use the PerkinElmer TurboMatrix headspace FID for the analysis, assuring you of the highest quality to attain reproducible results.
Note: Due to the patent which PerkinElmer holds on the closures system of the Headspace vials, the caps, septa, and star springs cannot be sold separately.
