What min temp is a hot air oven used at?

Explanation:
Dry heat sterilization uses hot air and relies on higher temperatures because heat transfer without moisture is slower, so longer exposure is needed to kill microbes. Because of this, a hot air oven is used at a relatively high minimum temperature to ensure effective sterilization. Around 150°C is considered the lowest practical setting for this method, with many procedures actually using 160–170°C (or even 170–180°C) for 1–2 hours depending on the load. Lower temperatures would not reliably sterilize due to slower heat transfer and greater resistance of some spores.
