Virucidal Testing

Virucidal testing measures the efficacy of disinfectant claims on virus killing. Efficacy data must be provided to register a virucidal disinfectant for market release. ImmunitasBio has experience in testing many different disinfectants against an assortment of viruses. To ensure virucidal testing is done precisely and effectively, it must be done according to a set of standards.

Our testing is done in compliance with EN or ASTM standards. Test methods may be modified to meet your testing needs. Viruses may be acquired, as necessary. Our test includes tight controls that can give clients a high level of confidence in their test results.
