When loading a steam sterilizer, how should basins be positioned?

When loading a steam sterilizer, basins should be positioned on edge to ensure optimal steam penetration and adequate drainage during the sterilization cycle. This orientation allows for the steam to circulate effectively inside and around each item, which is crucial for achieving sterilization. Additionally, placing basins on edge helps prevent water pooling, which can lead to inadequate sterilization and compromise the sterility of the instruments.

When basins are stacked vertically or laid flat, the steam may not reach all surfaces uniformly. Stacking could create barriers to steam penetration, while flat positioning might lead to moisture accumulation in the basins, both of which could hinder the sterilization process. Laying basins upside down is ineffective as it does not facilitate proper steam contact, significantly reducing the likelihood of successful sterilization.

Thus, the proper positioning of basins on edge is essential for ensuring thorough sterilization when using a steam sterilizer.
