Leak testing, which is part of manufacturing catheters, catheter balloons, luer connectors, dialyzers, IV bags, and respiratory gas filters in medical technology contexts, is a highly sensitive process with strict standards to meet.<\/p>\n
From determining the lowest measurable leak rates and performing measuring instrument capability investigations to identifying required cycle times, we have developed a range of solutions with our finely honed expertise in leak testing. We have what it takes to support you from product and process development through high-volume production.<\/p>\n<\/div>\n
SMALL COMPONENTS<\/h3>\n\nBecause of their size, miniaturized valves made from silicone and other plastics are challenging to deal with in leak testing. Non-return valves, for instance, require not only leak testing but also opening pressure detection at minimum diameters.<\/p>\n<\/div>\n
Small component volumes<\/h4>\n\nFor applications involving our ZEDcore modular measuring unit, we have developed an external valve block that minimizes the volume on the device side \u2013 allowing even the smallest volumes to be tested efficiently.<\/p>\n<\/div>\n
Minimum permissible leakage rates<\/h4>\n\nThe entire ZED device family, which includes the ZEDbase+, comes with our modular ZEDcore measuring unit featuring highly sensitive sensor technology \u2013 allowing even the lowest leak rates to be detected reliably.<\/p>\n<\/div>\n

\nThe structure and complexity of catheters<\/strong> make them challenging to deal with in leak testing. We test:<\/p>\n\n- Single-lumen, multi-lumen, and PTCA catheters: leak testing, flow testing, burst pressure testing<\/li>\n
- Flushing systems: leak testing, flow testing<\/li>\n
- Hose systems: leak testing, flow testing<\/li>\n<\/ul>\n<\/div>\n
Volume instability<\/h4>\n\nWe have made the testing process even better with a customized pre-filling process that stabilizes the volume during the measurement time.<\/p>\n<\/div>\n
