What is the recommended time and temperature for rapid heat transfer in dry heat sterilization?

In dry heat sterilization, heat moves to instruments through dry air, which is slower than moist heat, so using a high temperature for a shorter time helps achieve sterility quickly. The recommended combination of 12 minutes at 375°F provides a high enough temperature to penetrate and kill organisms while keeping the exposure short to reduce the risk of heat damage to instruments. This balance is why 12 minutes at 375°F is preferred for rapid heat transfer. The other options either use temperatures that aren’t high enough or exposure times that are too long or too short to reliably achieve sterilization without unnecessary risk to the load.
