Our field of operation
For over 30 years this medium sized Saxon company has been developing, designing, and manufactouring technologically sophisticated particle analysis and sensor systems in Germany under the Topas name to generate, condition, and analyse aerosols. Our equipment, over 60+ series-devices and 20 test systems, has been widely used in the classification and testing of air filters and filter media for global industrial applications, as well as basic research, and has been successfully proven for decades.
Applications for our products
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.
