This paper presents the Experimental Study of Plasma Generation which is used for ensuring quality of Evacuated Vials (Vacuum vials), using an electronic circuitry making it safe and much more economically feasible. Evacuated vials are widely used in Pharmaceutical Industries. Reliable test of the batches of Evacuated Vial must be done before dispatching these for the use of customer. There can be problems involved in checking of these vials, as the conventional devices are either unsafe or expensive. There are numerous methods for Generation of Plasma, among which our experimental study is based on RF Corona Discharge method for achieving Experimental Output. In this demonstration evacuated vials have being exposed to high frequency high voltage which creates a large Electric Field. Due to this field electron-positron pairs are produced in vacuum thus making it electrically conductive. Due to phenomenon of Corona Discharge a Violet Spark is observed in the vial, this violet spark is only the plasma. This demonstration can be used to confirm presence of sufficient amount of vacuum in the vial.
