What is sterile water?

Sterile water is free from all microorganisms like bacteria, spores and fungi. In medical environments, tap water isn’t safe for use when sterilising medical equipment. This is because it can contain bacteria that could contaminate this equipment. In contrast, sterile water is free from these organic materials.

Is sterile water the same as distilled water?

Sterile water is not the same as distilled water. Sterile water doesn’t contain organic substances, but may contain some inorganic substances like minerals. In contrast, distilled water contains neither organic nor inorganic substances, so it’s as close to H20 as possible.
