Under UV sterilisation, how often should tools be turned over?

Explanation:
UV sterilisation relies on direct exposure to UV-C light, and light doesn’t reach around edges or through shadows. Because of that, you must turn tools so all surfaces face the lamp and receive irradiation. Turning at intervals helps ensure every side gets enough exposure; a 20-minute interval is used in many protocols to balance effective irradiation with practical handling. If you turn more often, you’re just adding unnecessary handling time; if you wait longer than 20 minutes between turns, some surfaces may not receive sufficient UV exposure, risking incomplete sterilization. So turning over every 20 minutes ensures comprehensive surface exposure and effective sterilisation.
