Lippke 5000 - Seal strength and pressure leak testing

Measure seal strength and package integrity with the Dansensor® Lippke® 5000. Perform burst, leak, creep, creep to fail and bubble tests from one instrument – or try the combined test option to conduct a simultaneous leak, creep and burst test on a single package. It is ideal for testing rigid, semi rigid and flexible packaging, as well as porous and laminated foils for the food, pharma and medical industries.

With an extensive array of features, test options and accessories, it meets applicable ISO and ASTM standards. In addition, the instrument features individual logins and different user levels to ensure the data security and traceability required by healthcare and pharmaceutical customers.

The leak test systems provide manufacturers with an idea of how well packages resist pressure. Measuring seal strength and carrying out pressure leak tests are important prerequisites to delivering strong and lasting packaging that have a low risk of bursting under pressure.
