Log10 steps | HARTMANN SCIENCE CENTER

Measure to describe the reduction of microorganisms. Example: With an initial figure of 10⁶ germs per ml (the log₁₀ value equals 6) and a disinfectant that reduces the number to 10³ germs per ml (the log₁₀ value equals 3) the number of microorganisms is reduced by 3 log₁₀ steps.

Mechanism of action

The active substances of chemical disinfection procedures attack pathogens using a certain mechanism in order to kill or inactivate them. Examples: Alcohols have an unspecific mode of action. They denature all proteins, thus inhibiting...

Spectrum of activity

Microorganisms are very diverse therefore it is difficult to find a disinfectant that is effective against all of them. Find out here more about the spectrum of activity of disinfectants.
