What is technical cleanliness?

Terms such as technical cleanliness, residual dirt and particles are appearing more and more frequently when it comes to product quality. Increasingly complex technical systems are sensitive to foreign particles. Sliding surfaces are damaged, valves are blocked, short-cirquits occur.

Regular technical cleanliness tests can help you to prevent the failure of components or damage in their operating environment. In this way you avoid delivery difficulties, protect your customers, avoid claims for replacement or rebates and ensure your company’s good reputation through consistently high quality

Technical Cleanliness

With analyses of technical cleanliness, we ensure that your products do not only make a good impression on the surface. The aim is to ensure smooth operation and a long service life.

Residual dirt analysis

How clean is a component after completion or at certain production points? The residual dirt analysis is the basis for statements on technical cleanliness.


With our particle traps, in addition to the direct examination of components, it is possible to determine the cleanliness of the assembly environment or individual workplaces.

Fluid examination

In hydraulic systems, the cleanliness of the medium used plays a decisive role for the smooth functioning and service life of numerous components.

Industry sectors


The cleanliness of many components is essential for the safety and smooth operation of every modern vehicle.


Products containing electronics are particularly sensitive to conductive particles.

Medical technology

Cleanliness in every form has always been of vital importance in medicine

Mechanical engineering

Hard foreign particles in particular can have a considerable impact on the mechanical bonding of components.


Contaminated foodstuffs and their packaging even pose a health risk to the consumer.


Also for products such as optics, lubricants, cosmetics, children's toys etc. contamination with particles is disadvantageous.
