At interpack 2017, Bosch Packaging Technology presents the new KLV series for Container Closure Integrity Testing (CCIT). “In the pharmaceutical industry, non-destructive CCI technologies are becoming increasingly important,” explains Dr Jérôme Freissmuth, product group head at Bosch Packaging Technology.
“Even the smallest leaks can be highly hazardous for patients. The active ingredient could alter, administering the medication could lead to serious side effects as a result of non-sterility, or the medication could become ineffective. Furthermore, non-destructive integrity testing protects pharmaceutical manufacturers against the loss of valuable medication, since the container remains intact during testing.”

High voltage leak detection and laser-based headspace analysis are now complemented by the new KLV series for vacuum leak detection. At Interpack, Bosch unveils the first in the series – the KLV 1360, which has been specially developed for vials. Generally, the platform is suited for all rigid glass containers.
Highly sensitive testing combined with high output
“A special feature is the combination of testing sensitivity and high output,” says Wolfram Schindler, engineer measurement technology at Bosch Packaging Technology. In vacuum leak detection, negative pressure is created in hermetically sealed chambers. If the container is faulty, the leaking fluid or gas causes the pressure to rise. The KLV 1360 measures this pressure increase with very high sensitivity. Thanks to state-of-the-art measuring technology, the machine is able to measure leaks equivalent to hole sizes of less than five micrometers.
The KLV 1360 can inspect between 250 and 600 containers per minute. It achieves its maximum performance thanks to special inspection chambers, where the containers can be tested either individually or in groups. “Depending on the body diameter – which can vary from eight to 56 millimeters – the KLV can inspect up to three containers simultaneously in one chamber. This enables us to significantly increase the output,” Schindler explains.
Maximum protection even after inspection
The KLV ensures a consistently high inspection quality. It is the first machine of its kind where the integrated robotic system not only feeds the containers that require inspection into the process. It also adds reference samples for internal process control. In addition, automatic re-inspection makes sure that only containers, which have clearly been tested, leave the machine.
Even after inspection, the product and closure quality remain a top priority. The KLV does not grip the containers from above. Instead, the slightly slanted transport system makes it possible to remove the conatiners from the inspection chamber sideways in order to prevent leaks occurring due to closure gripping. Furthermore, a star-wheel system ensures gentle transportation through the system with minimal wear and tear. Thanks to its modular construction, the KLV 1360, which has a turntable fitted as standard, can be seamlessly integrated into existing lines.
Everything from a single source
The new KLV 1360 completes Bosch’s inspection portfolio. Visitors to interpack can learn about the entire range of technologies – from visual inspection and headspace analysis to vacuum testing, all of which will be showcased as benchtop models. “Our customers not only have a wide choice of technologies,” Schindler underlines. “We also advise them on the best inspection solutions for their liquid or lyophilized medications and are their experienced partners when it comes to regulatory requirements and individual solutions.”
