MethodAgentTimeNotes
SterilizationPressurized steam (autoclave)20 minutes at 121°C and 103.5–140 kPa pressureAssumes the areas of equipment targeted for decontamination are accessible to steam. Time should be increased to 30 minutes for wrapped items.
2% glutaraldehyde5 hours contact at 20–25°C with a 2% activated alkaline formulation (pH = 7.5–9)Some sources/manufacturers suggest 10 hours for sterilization.
High-level disinfection (HLD)Chlorine (sodium hypochlorite)5 minutes contact at 20–25°C with buffered hypochlorite (pH = 7–8) at a concentration of 5000 ppm available chlorine (approximately 10% dilution of household bleach – can be corrosive to metals)Some sources recommend 20 minutes in a 5% dilution if made with tap water, or 1% dilution if made with boiled water.
2% glutaraldehyde30 minutes contact at 20–25°C with a 2% activated alkaline formulation (pH = 7.5–9)Some sources/manufacturers suggest 20 minutes for HLD.
Boiling20 minutes at a “rolling boil”The pot should be covered; items that float do not need to be fully immersed.

Note: the effectiveness of all sterilization and HLD techniques depends on prior cleaning to remove organic matter or material that is dried and adherent to the equipment (123, 125, 126).
