Electrostatic discharge of plastic syringes

How are syringes filled?

A pharmaceutical plant fills syringes with a liquid.

What problems can arise during filling?

The syringes are inserted manually into a magazine. As the operators have to wear plastic gloves when inserting the syringes, the syringes become electrostatically charged! When filling the syringes, the liquid to be filled is deflected by the electrostatic charge. As a result, the syringes can no longer be filled properly.

Our Solution

Problem solved by using a very uniformly working ionization bar, which was installed movably. The power supply operates with improved ion balance.

blueBAR R50

The robust all-rounder bar The VARIO discharge bar blueBAR R50 creates a significantly higher active discharge capacity than most discharge techniques. The isolated ground conductor enhances the E-field at the active tips, contributing to increased production and velocity of charge carriers. Thus, significantly more positive ions and free negative electrons are available than with conventional bars. At the same time, the bars have a high passive discharge capacity. The resistance-decoupled tips ensure good discharge performance and make the bar absolutely short-circuit and touch-proof.
