Survey "Sterility Validation in Medical Technology"

In medical technology, the concept of purity has been deeply rooted for many years and is codified in regulations. Nevertheless, there are recurring problems that can be attributed to a lack of product purity. There are also aspects of production technology where excessively high purity requirements…

Application example and benefits

Energy monitoring for cleanroom technology systems

Through specialized energy monitoring, time-synchronized measurement and consumption data of air handling systems (AHUs) can be recorded. The optimization potentials identifiable with this, especially in the control technology sector, can lead to significant energy and cost savings without violating…

Filter leak test: Analysis of moving sampling probes

In the cleanroom laboratory at Offenburg University of Applied Sciences, investigations were conducted into the airflow conditions around moving sampling probes and their detection behavior. The results show that it would be sensible to standardize the key parameters of manual leak testing in conjun…
