Ultrapure water is water from which all foreign constituents such as ions and organic components have been removed. Only water that meets certain criteria may be called ultrapure water.

Only one type of water is ever referred to as ultrapure water. However, there are various gradations, which are then referred to as pure water. Norms and standards take up and categorize the different physical properties such as conductivity, resistance, TOC content, ion concentration and bacteria content. Important definitions exist according to ASTM (American Society for Testing and Materials), ISO (International Standards Organization) and CLSI/CLRW (Clinical Laboratory Standards Institute/Clinical Laboratory Reagent Water).

Ultrapure water is one of the most commonly used solvents in the laboratory and is used wherever even minor impurities lead to falsification of results and must therefore be avoided at all costs:


- Analytical methods such as AAS, ICP, MS

- Chromatography such as LC (mobile phase)

- Sample preparation (extraction, dilution, blank)

- Biological work (PCR, cell culture, immunochemistry)

- Forensic and clinical examinations

In addition to ultrapure water, pure water also finds a large field of application in laboratory use, although the requirements for the degree of purity of the water are lower:

- Preparation of media and buffers

- General laboratory applications such as cleaning laboratory equipment

- Feeding of
laboratory dishwashers,
steam generators
systems for the production of ultrapure water

Drinking water itself contains impurities and will give a false result in your analytical tests, so you cannot use tap water in the laboratory.
Molecular biology work requires water without pyrogens (biological metabolites). By using ultrapure water in which the interfering impurities have been removed, reliable and accurate results are obtained.

Various purification technologies are used to produce pure water first and ultrapure water later. Step by step, the impurities are removed from the water and finally water with the required purity level is made available to the end user. The purification technologies include
- Filtration by activated carbon
- reverse osmosis
- Ion exchanger
- Electrodeionization (EDI)
- UV light
- ultrafiltration (UF)

For the selection and combination of these techniques, the prevailing degree of purity of the source water as well as the degree of purity to be achieved in the water to be used are decisive.
