In support of this fact, it has been found that the presence of moisture significantly affects the coagulation temperature of proteins and the temperature at which microorganisms are destroyed. Chemical HLD. This point is illustrated with the decontamination of 10 lbs of microbiological waste, which requires at least 45 minutes at 121C because the entrapped air remaining in a load of waste greatly retards steam permeation and heating efficiency.831, 832The high-speed prevacuum sterilizers are similar to the gravity displacement sterilizers except they are fitted with a vacuum pump (or ejector) to ensure air removal from the sterilizing chamber and load before the steam is admitted. immediately to prevent it from degrading, but dont use dry heat.
