The septum is die cut from sheet material with a steel die. The glass vials are made from glass tubing that has the bottom and threads machined by a fine flame. Between the cap mold, die cut septa and machined vials, the mold has the smallest plus or minus tolerances, followed by septum die and the machined glass vial.

sterile 40-mL clear VOA vials containing MS broth and capped with septum valve caps (Mininert). For controls, there were additional six vials containing MS broth without plants. CPS was added to the solution to a final concentration of 25 µg/mL through the mini-nert valves using a glass gastight syringe (Hamilton, Reno, NV).
Screw cap may be used for capping water samples in amber glass vial comprising of a polytetrafluoroethylene silicon septum for the analysis of chlorinated volatile organic compounds in water samples using headspace-solid-phase microextraction with gas chromatography (HS-SPME-GC).
The vials should be completely filled at the time of sampling, so that when the septum cap is fitted and sealed, and the vial inverted, no headspace is visible. The sample should be hermetically sealed in the vial at the time of sampling, an d must not be opened prior to analysis to preserve their integrity.
