Is there a most commonly used reaction you can encounter in every type of lab? You know the answer! Water. It is found in all types of labs medicinal, pharmaceutical, chemistry or microbiological.

They require different levels of purity of water for the various levels of sensitivity they require for their analyses and experiments. You can buy pure water through

The entire process of water purification is lengthy and involves several steps. The most popular purification procedures employed to clean water from impurities are the following:

1. Distillation – The water is heated, and the condensed vapor is absorbed and filtered. However, there remain impurities that can be found in distilled water like ammonia, silica, and other organic substances. The storage of distilled water is essential to protect it free of contamination.

2. Reverse osmosis – Osmosis is the process of moving water from a higher concentration to a lower concentration due to the pressure of osmosis. In reverse osmosis water is filtered with greater pressure than the osmotic pressure to remove impurities.

3. Ion exchange takes out various metals, including heavy metals that are present in water, however, the process of ion exchange can keep microorganisms.

4. Activated Carbon – Also called adsorption media, it is effective in removing chlorine from water through "a catalytic mechanism as well as dissolved organic matter through Adsorption".

5. Ultraviolet disinfection is the use of ultraviolet light, which is a potent sterilizing agent that kills microorganisms and bacteria.

6. Filtration Water filtration using different pore sizes will ensure that other impurities of different sizes are kept out and the water remains free of contamination.
