Sediment-free plasma sealing – aseptic closure of glass vials

Sealed glass vials are considered the most secure containers for storing parenteral fluids. The vials are conventionally closed with a gas/oxygen mixture, whereby a propane/butane or natural gas is used as the burner gas. Depending on the adjustment of the gas mixture, this process can result in sediment and soot buildup in the inside of the vials, thus contaminating the contents. To address this problem, Plasmatreat has developed a special Openair® jet technology with the highest plasma performance and 100% reproducible process parameters.

In this process, the plasma energy is targeted to achieve aseptic closure of the glass vials.
Since the plasma flame does not burn in the conventional sense (combustion, oxidation), no exhaust or soot forms, and there is thus no contamination by flame reaction products.
