Maintaining aseptic conditions in a water sample is extremely difficult. However, the presence of culturable organisms can be determined by plating out the organisms on suitable growth media and counting the number of colony forming units. The results can then be expressed in terms of CFUs/l of water.

Can I Substitute boiled water for distilled water?
Boiled water is not the same as distilled water. Distilled water has been purified by a distillation process, which removes impurities and minerals. Boiling water may kill bacteria but it does not remove impurities, so it is not a suitable substitute for distilled water in applications requiring high purity.
What is the difference between sterile distilled water and sterile water?
Sterile distilled water has no microbial contamination and is distilled and and sterile water merely has no microbial contamination.Distillation is the process of separation by heating a liquid until it evaporates and then condensing the steam back into a purer liquid as all contamination remains in the part which does not evaporate.
Is distilled water the same as distillation?
Boiled water is not the same as distilled water. Distilled water is boiled until it turns to steam, as the steam cools the water is recollected, so what you have is pure water. Boiled water is boiled just until it is sterilized and bacteria has been removed.
Will boiled distilled water no longer have oxygen?
Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
What is the difference between boiled water distilled aater and tap water?
Boiled water is heated to kill harmful bacteria and microorganisms but may still contain impurities. Distilled water is boiled and then the steam is condensed, resulting in water free of most contaminants. Tap water comes directly from the municipal supply and may contain minerals, chemicals, and other impurities depending on the source.
Is boiled water distilled water?
No, boiled water is simply boiled. Distilled water is when the steam from the boiling is gathered and rebottled.
Can you use sterile water in place of distilled water in a cigar humidor?
Yes. Just make sure it is a medical grade sterile water. Don't use boiled tap water. Ideally you should use propylene glycol (PG) as well.

Are sterile water and sterile distilled water the same?
no. Distilled water has had all chemicals and minerals removed, usually by steaming and re-condensation. Sterile water has been treated, usually heat treated, to destroy pathogens (any living organisms). So, you can sterilize distilled water, but not all distilled water is sterile. manufacturing criteria do NOT require that regular distilled water be packaged to prevent contamination. Water sold as sterile water must be packaged to avoid contamination. On the other hand, water full of minerals can be sterilized; the minerals are still present. So if you want mineral free, organism free water, you need sterile distilled; if just mineral free, distilled.
Can you use boiled water in battery?
No, only use distilled water.

How is water distilled?
Distillation is achieved by boiling the water and collecting and cooling the evaporate in a sterile container.

Is flouride in distilled water?
No. Fluoride does not break down when water is boiled and remains in the distilling vessel.
Can you use sterile water in autoclaves instead of distilled water?
It is not recommended to use sterile water in autoclaves as it may contain particles or impurities that could interfere with the sterilization process. Distilled water is preferred in autoclaves because it is free of impurities and minerals that could cause buildup and affect the equipment.
