Seal Integrity Monitoring System

The most current model, the Seal Integrity Monitoring System (SIMS) 1915+, is the ideal choice for your helium based leak detection system. Using helium as the tracer gas, packages can be quantitatively tested to levels far exceeding the vacuum bubble and dye penetration test methods. This quantitative approach allows direct comparison across various packaging materials and forms, production line settings and stability storage conditions, supporting the entire lifecycle.


The LDA SIMS 1915+ can be used for package design, tooling qualification, production line setup and on-going product quality monitoring and is a proven and effective method for a variety of package types including cold form blister cards, foil pouches, parenteral vials, syringes, pre-filled syringes and unique medical devices.

Each SIMS 1915+ Helium Leak Testing instrument manufactured by Leak Detection Associates is custom built to client-specific standards. Key factors that determine instrument build specifications include:

  • What type of package(s) will you be testing with this instrument – Vials, Blister Cards, Syringes, Cartridge System or Medical Device? Size and closure type should be included and whenever possible a schematic of the package or device can be helpful in optimizing the test system.
  • Projected amount of use the instrument will see?
  • Country where the instrument will be installed?

Leak Detection Associates Seal Integrity Monitoring System (SIMS) Model 1915+ helium-based leak testing system features an oil-free pump, detector and integrated power system that is designed for the needs of the pharmaceutical and medical device industries, enabling quantitative analysis of package systems at sensitivity levels as low as 1 x 10 -10 cc/s at room temperature. The most critical component, the Helium Leak Detector Module (HLDM), is engineered into a Console Frame Assembly that features a Stainless Steel working surface and optional Dual Test Port Manifold. The consoles are fitted with a locking wheel an articulating arm system for mounting of the computer and peripherals, making the freestanding unit easy to use and maneuver.
