Quality Classification Of Laboratory Use Water
There are four levels of water purity recognized in the water purification across the industry, each of which are used for specific applications in laboratories, the quality of water is defined through a series of measurements of:
Quality is dependent on its source. Whilst deep water is naturally filtered by layers of rock and soil, surface water is inferior and has risk of environmental contamination. The most common type of pre-treatment are depth-filters made of series of fibers to trap impurities and softeners to reduce the harness level Apart from quaity, major significance of such treatments is to extend the lifespan of RO membranes (reverse osmosis) which is an unavoidable process for further purification.
Type 3 water is most commonly used as the starting point for many applications in laboratories, including feeding glassware washing machines and autoclaves. It can also be used as a pre-treatment for ultrapure water systems, or anything that’s considered non-critical. Type 3 water uses carbon filtration and RO technology with 99% of feed water contaminants removed, therefore is also called RO water. As these treatments are only preliminary, quality of RO waters can’t be specifically classified.
Type 2 water is generally used for applications such as buffer and media production, general chemistry and spectrophotometry. Type 2 water is normally obtained through a combination of RO and EDI (ion exchange or electrical ion exchange) technology. EDI is a deionization process where all unwanted ions are replaced by hydrogen and hydroxyl ions, which form pure water once combined. Type 2 water needs to have a resistivity of 1~15MΩ-cm.
Ultrapure (Type 1) water is a must for analytical laboratories which typically includes flow cytometry, pyrogen-sensitive applications, and cell and tissue culture. Apart from RO & EDI technology, normally UV lighting process and ultrfilters(UF) are normally added to control Bacteria and organic level at a low level and be DNase/RNase free. Ultrapure (Type 1) water needs to have a resistivity of 18.2 MΩ-cm at 25°C .
