Our 2mL crimp top vials are constructed from type 33 and type 51 COE borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. By choosing our caps and septa, you provide your sample with a the best containment solution available. Features: Multiple cap colors and septum options

Oct 10, 2020 · By combining the current study results, the optimal analytical conditions could be described as follows: A head space vial of 10 ml is used, a sample mass of 200 mg is recommended, in which 1.25 mL ISTD solution is added. Next, a cap using metal liner and PTFE septum is applied and put in an ultrasonic bath for 90 min.
