E-Scan 655 MicroCurrent High Voltage Leak Detection HVLD

E-Scan 655 deterministic HVLD technology is the optimal solution for all parenteral and biologic products. 

The E-Scan 655 is a revolutionary deterministic offline micro leak test instrument that utilizes a new class of HVLD technology to inspect vials, syringes, and other liquid filled parenteral products for container closure integrity. The E-Scan 655 technology is a MicroCurrent conductivity test method, HVLDmc, that is completely non-destructive to the container and product; exposing the package and product to lower voltage than other conductivity based solutions. The technology uses a non-contact and non-invasive test method that requires no sample preparation.  E-Scan 655 can be used with a wide range of liquid based products including low conductivity sterile water for injection (WFI) and proteinaceous products with suspensions.

The E-Scan 655 features a fast test cycle and simple operation. Additional benefits include quick changeover and easy recipe setup to accommodate a wide range of products and applications. The offline E-Scan 655 method can be migrated from laboratory to 100% inline testing applications at high production speeds.
