Leak Detection Systems
NORDTEST is a leading supplier of non-destructive package inspection technologies for the pharmaceutical, medical device, food and container industries. We offer inspection systems for package integrity testing, seal integrity and leak testing.
NORDTEST is a leading supplier of non-destructive package inspection technologies for the pharmaceutical, medical device, food and container industries. We offer inspection systems for package integrity testing, seal integrity and leak testing. Our technologies exclude subjectivity from package testing, and use test methods that conform to ASTM and EU standards. Our leak testing systems, manufactured in the US by PTI Inspection Systems, provide repeatable, reliable results and can be incorporated into protocols at any point in the manufacturing process as they are non-destructive, non-invasive and require no sample preparation.
Our leak testing and container integrity testing technologies include high-voltage leak detection (HVLD), vacuum decay, pressure decay, and non-contact ultrasound, and allow for testing of ampoules, empty and pre-filled syringes, blow fill seal, blisters, bags, IV bags, pouches, liquid and dry filled pouches, liquid filled vials, lyophilised vials, bottles and containers, cans, single serve, cups filled/sealed, and trays.
We also supply non-invasive headspace online analysis based on laser absorption spectroscopy.
Seal quality inspection (non-contact ultrasound technology)
Seal-Scan® characterises seals (thermal seals, ultrasonic seals, bounded surface seals) that appear visually acceptable yet possess defects that affect product quality and shelf-life. Seal-Scan systems utilise non-contact airborne ultrasonic technology for seal integrity testing and seal quality analysis of pouches and flexible packaging. Testing is non-destructive, non-invasive and requires no sample preparation. Ultrasonic technology allows for fast on line testing but also for accurate informative imaging of seal quality.
Package integrity testing and micro leak testing (vacuum decay leak test technology)
VeriPac inspection systems evaluate and analyse package integrity with precision and repeatability. VeriPac systems can be easily integrated into the packaging process to improve quality, reduce waste, and provide operators with a clearer understanding of package quality. Test systems are non-destructive, non-invasive and require no sample preparation. Test fixtures are designed to inspect flexible, rigid and semi-rigid packaging.
VeriPac inspection systems utilise an ASTM-approved vacuum decay leak test method recognised by the FDA as a consensus standard for package integrity testing. This ASTM method was developed using VeriPac leak test instruments and has proven its capabilities under GMP regulatory guidelines.
VeriPac 455 is a non-destructive inspection system for highly sensitive micro leak detection of empty and pre-filled syringes, liquid filled and lyophilised vials and other liquid filled packaging (both flexible and rigid). The VeriPac 455 features patent pending dual vacuum transducer technology that offers increased test sensitivity and produces very consistent, reliable results.
The VeriPac D-Series are versatile non-destructive package inspection systems specially designed for pouches and flexible packaging. VeriPac inspection systems provide a qualitative result (PASS or FAIL) as well as quantitative data that correlates to leak rate and leak size. To accommodate various package specifications and test sensitivity requirements, the VeriPac D-Series is available in several configurations for both the leak test instrument and the test chamber capacity.
Micro leak testing (high-voltage leak detection)
The E-Scan 625 is an offline lab instrument that utilises high-voltage leak detection (HVLD) leak detection technology to inspect individual samples for container closure integrity. HVLD is completely non-destructive to the container, and is a non-contact, non-invasive test with no sample preparation required. Package/container material must be non-conductive (glass, plastic, poly laminates).
HVLD can be used on a wide range of liquid-based products, including products with suspensions, emulsions and protein. HVLD has proven to be a highly sensitive leak test method for various types of pharmaceutical packaging (pre-filled syringes, liquid filled vials, blow-fill-seal containers, IV bags and other liquid filled pouches). PTI also offers the same technology for on line application up to 24,000 pcs/hr.
Blister package inspection (vacuum decay and vision technology)
The VeriPac 225/BLV inspection system evaluates and analyses blister package integrity with precision and repeatability. The core technology of the VeriPac 225/BLV is based on an ASTM-approved vacuum decay leak test method that was developed using VeriPac instruments, with the addition of special vision imaging technology to easily identify the location of defective blister cavities.
The VeriPac 225/BLV provides non-destructive, non-invasive inspection of multi-cavity blister packaging made with any material, flat or glossy finish, printed or non-printed surface. Each test cycle is rapid with test results available in numerical, statistical and image formats.
Bottle and container leak testing (vacuum / pressure decay)
VeriCon inspection systems are a complete line of leak testers for empty bottles and containers. To accommodate various container specifications, line speed, handling and test sensitivity requirements, VeriCon systems are available in configurations including linear leak testing, continuous motion leak testing, and trimmer units for indexing installations. All VeriCon systems utilise high-resolution non-drifting transducers (either pressure transducers or vacuum transducers) for consistent leak detection.
