What temperature is thermal disinfection?
What temperature is thermal disinfection?
A The final rinse phase in a washer disinfector is when thermal disinfection actually takes place. The hot water, at a minimum of temperature of 180 degrees, acts as a conduit which delivers the required temperature to all of the surfaces and crevices of the instruments and other items in the washer.
How do you get thermal disinfection?
Thermal disinfection is defined in the ISO15883-1:2006[1] standard as, ”disinfection achieved by the action of moist heat.” This can be performed by exposing devices to hot water, steam, or a combination of the two.

What does a thermal washer disinfector do?
Thermal Washer Disinfectors enable you to achieve safe, visible cleaning and disinfection results for dental instruments. They are particularly gentle on the instrument material and are recommended by reputable manufacturers for preparing transmission instruments.
What is the time temperature relationship for thermal disinfection?
Thermal disinfection can be characterized by the A0 concept. The improvement of lethality with hot water temperature can be predicted. For instance, for heat resistant microorganisms, 10 minutes at 80°C has the same lethality effect as 1 minute at 90°C or 100 minutes at 70°C.
What is physical disinfection?
Physical means of disinfection do not involve the addition of chemicals, but disrupt normal microbial function or cause structural damage to pathogens through physical means. An effective physical disinfection process is safe, energy efficient, consistently effective, and cost-effective at a larger scale.
