Descrizione

Descrizione generale

Questi flaconcini richiedono un tappo speciale con filettatura da 18 mm. I tappi filettati 18-400 standard non sono adatti a questo flaconcino. I codici prodotto dei tappi disponibili per questi flaconcini sono i seguenti: SU860101(con PTFE/silicone, spessore di 1,3 mm), SU860102 (con PTFE/butile, spessore di 1,6 mm) e SU860103 (con PTFE/silicone, spessore di 1,5 mm). Questi tappi sono prodotti in acciaio inossidabile e sono magnetici.

Applicazioni

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.
