What are the recommended autoclave settings?

Explanation:
Moist-heat sterilization relies on steam under pressure. At about 15 psi, the steam reaches roughly 121°C (250°F), a temperature reliably capable of killing bacteria, viruses, and spores. Setting the autoclave to 250–270°F at 15 psi matches standard practice and provides effective sterilization, usually with a cycle time of about 15–20 minutes depending on the load. The other options fall short because they’re outside the effective range: temps around 180–190°F at 10 psi won’t achieve full sterilization, while 300–350°F at 20 psi can risk damaging instruments and seals.
