The french laboratoire Pasteur in Lille
conducted a study demonstrating the usefulness of Tactys keyboards in the fight against infections compared with the usefulness of keyboards made of silicone.
Following artificial contamination with two different types of keyboard bacterial strains (Pseudomonas aeruginosa et Staphylococcus épidermidis, about 106 bacteries per square inch), the surfaces are cleaned using disinfectant wipes. Thirty minutes later, the quantities of bacteria on the keyboards are measured again. This operation is performed three times for each bacterial strain and on the entire inventory.
The study concludes that after disinfecting the surface, the average number of bacteria is reduced by 4 powers of ten (10,000 times) on a Tactys keyboard compared with 2 (100 times) on a silicone keyboard.
