MicroCurrent HVLD technology is the CCIT solution for all parenteral and biologic products.
Referenced in the new USP <1207> Chapter Guidance as a deterministic test method for container closure integrity testing.
The E-Scan testing process uses a set of electrode probes to scan a non-conductive container that is sealed. The container material can be glass, plastic, or poly laminate. The container or package must contain liquid (minimum fill 30%). If a pinhole, crack, or other defect is present, there is a resistance differential and change in current flow indicating a breach in the container. The approximate defect location can be identified.
MicroCurrent HVLD can be used on a wide range of liquid based products including extremely low conductivity sterile water for injection (WFI) and proteinaceous products with suspensions.
PTI’s patent pending technology uses a unique mode of MicroCurrent HVLD, applying no more than 50% of the voltage used on conventional high voltage technologies. The MicroCurrent applied to the product during the test greatly reduces the voltage exposure to the product and environment. In fact, using MicroCurrent HVLD reduces voltage exposure to the product to less than 5% of the voltage exposure experienced when testing with comparable HVLD solutions.
