Our field of operation

Since more than 30 years, technology-oriented particle, analysis and sensor systems have been developed, designed and manufactured under the name Topas. They can be used to generate, condition and analyse test and reference aerosols. In addition, more than 60 series devices and 20 test systems of our medium-sized Saxon company have been widely used and proven for the classification and testing of filters and filter media in worldwide industry and basic research for decades.

Adaptable, dynamic, communicative: our new dilution system DDS 560/C

High flexibility and a dynamic system that does not restrict customers to a single volume flow rate and dilution factor are key features of the DDS 560/C. It has now been further developed by our engineers and comes with a clear display layout. This offers options for customised settings and thus extended access to internal device parameters such as the dilution factor or the volume flow. The existing external interface enables the documentation of experiments because setting parameters are saved over time. A must-have in every laboratory: The DDS 560 is the dilution system that adapts to your needs. Regardless of whether you work in aerosol research, toxicology, cleanrooms, or filter testing.
