Innovative VirHealth protocols

VirHealth laboratory has developed robust and reproducible protocols for the transfer of dry inocula (virus, bacteria, mold) onto all types of surfaces.

This allows for the simulation of hand-to-surface contact contamination and provides a technical solution for contaminating hydrophobic surfaces.

Durability of antimicrobial surface coatings and antimicrobial agents containing material

Test methods attempt to simulate real-world usage by proposing experimental scenarios (ISO, EPA) to simulate the impact of physical and chemicals attacks throughout the life cycle of antimicrobial products.

Simulation of physical wear and abrasion.
Simulation of repeated exposure to biocidal chemical solutions.

Simulation of several week/months of periodic cleaning and disinfection

Dry/wet abrasion simulation according to client's need
