The equilibrium regular for an equilibrium reaction is often based on utilizing the next equation:
-inadequate length with the dynamic air removal stage, insufficient tightness (air leakage) of the sterilizer in the dynamic air elimination period by evacuation;
Plan monitoring confirms the VHP sterilizers capacity to supply lethality to really resistant bacterial spores.
