Water contains so many different compounds, making it impractical to measure them individually. If oxidised, water will produce the following fractions.
Ultraviolet (UV) light is used to disinfect water. Short-wavelength UV lamps wrapped in a pure quartz sleeve produce radiation at precise wavelengths of 185 and 254 nm.
Ultrafiltration (UF) uses a super fine but tough, selectively permeable membrane made of either polymer materials or ceramics to remove pyrogens (bacterial endotoxins) and nucleases. This method is critical to producing cost-effective water suitable for tissue culture.
Deionisation uses synthetic ion-exchange resins to chemically remove ions from feed water. As the water passes through the ion exchange resin beads, hydrogen and hydroxide ions are chemically exchanged with dissolved minerals to form water. Learn more here in this article.
Reverse osmosis (RO) is the most economical method of removing up to 99% of your feed water’s contaminants. It is a percentage rejection technology. The resulting product water is therefore dependent on the quality of the incoming water.
All laboratories rely on pure water to produce reliable and repeatable experiments. Avoiding contamination at the bench is essential to any biological methods and the water quality used for sample and solution preparation is as important as other reagents.
