We conduct electrical conductivity / high voltage leak detection (HVLD) testing on a range of package systems, including parenteral vials, prefilled cartridges and syringes, plastic containers and plastic bags or pouches.

HVLD testing can detect the presence of a leak and potentially its location in the wall of a nonporous package (whether rigid or flexible) that contains liquid product. This is because when a leak path occurs near an electrically conductive liquid, the electrical resistance will drop in the test sample, as evidenced by a spike in the current above the predetermined pass/fail limit.

This highly sensitive method even works to detect package defects such as clogs by product formulation proteins or salts. Stability studies support the use of this technology for nondestructive leak testing for a variety of product formulation types.
