Our contribution to fighting the Covid-19 pandemic is our antiviral testing, enabling customers with active surfaces, textiles, procedures or antiviral substances to bring their solution into application.
In our S2-lab, classical antiviral assays according to ISO 21702 (surfaces) and ISO 18184 (textiles) or for substance effects according to the RKI guidelines are done, but also innovative new assays employing a spray-nozzles to produce droplets and aerosols of virus suspension or barrier-function assays for protective agents. This way we focus on meaningful analysis adapted to the clients needs. We use Human Coronavirus 229E or Adenovirus Type 5 with competent cell-lines.
- Testing for antiviral effect, with a special focus on corona virus, for substances or solutions in reference to the RKI-guidelines
- Testing of textiles according to ISO 18184:2019, modified for corona virus
- Testing of surface effects against virus according to ISO 21702:2019, modified for corona virus
- Spray-nozzle assay to test the effect of surfaces, textiles, virus deactivation methods on virus activity in droplets and aerosols
- Barrier function analysis for substances that block of virus entry into model cells
- Adaptation of incubation time, protein or other load, temperature, light to analyse realistic application scenarios
Antiviral Testing and Surface Activity Assays
We realize antiviral testing to certify inactivating or blocking activity of your material, substance or method according to scientific standards using Human Coronavirus 229E as model. It is our pleasure to consult and explain the possibilities for your material, we are looking forward to your request.

How is antiviral testing done?
Step 1: Inoculation with virus
The samples in infected with a drop or a spray nozzle.
Step 2: Sampling
After a defined time of incubation, the virus is washed of the sample with a nutrient solution.
Step 3: Evaluation
The effect of the virus on competent cells is evaluated either by a plate count or a plaque formation assay. The titer of active virus is calculated.
