Description générale

The red rubber is "polybutyl isoprene."

Application

PTFE-red rubber, silver-septa with caps was used to close head-space vials containing essential Ocimum oils during solid phase microextraction (SPME), in an experimental study conducted for chemotaxonomical analysis of the essential oil aroma compounds of four different Ocimum species. It may also be used with headspace vials in Headspace Sorptive Extraction (HSSE) sampling coupled with Gas Chromatography-Mass Spectrometry (GC-MS), for the analysis of the volatile fractions and chemometric methods of pesto genovese and its ingredients.
Septa, PTFE/red rubber, pkg 100 may be used for a headspace glass vial in the analysis of the volatile fractions of pesto, a typical Italian basil-based pasta sauce, and its ingredients using headspace sorptive extraction (HSSE) followed by gas chromatography-mass spectrometry (GC-MS).
