Testable bacteria and viruses

We design tests and evaluative protocols around the client’s specific needs.

An open-ended approach to testing that goes beyond JIS standards allows us to further probe the veracity of a hypothesis and yield realistic results.

Test design examples

  • Example 1: continuous inoculation of bacteria

    We can design tests around actual usage contexts and inoculate a sample over multiple days in order to determine its antibacterial resistance over a given period of time.

  • Example 2: flexible time parameters

    We can design tests conducted at specific time intervals, which will allow you to assess antibacterial properties with a view to thresholds defined by JIS and other standards.
