With purified water commonly used as a reagent in a wide variety of scientific and clinical applications, it is vital to ensure the correct level of purity is achieved and maintained.


What is Type 1 Water?

Type 1 water is most commonly known as Ultra Pure water. It is water that has undergone a high level of purification in order to meet stringent water purity requirements. The water type defines the water specification regarding the level of contaminants (such as organics, ions, pyrogens and bacteria) within the water.

Type 1 water reaches the theoretical ideal levels of purity, with a resistivity level of
18.2 MΩ-cm. Water of this quality is required for semiconductors, power and laboratory applications.

Endotoxins are also removed, and as such, Ultra Pure water typically contains <0.03 EU/ml, with nucleases and proteases at non-detectable levels.

Type 1 Ultra Pure water is utilised in some of the most sensitive and critical applications including:

  • High Performance Liquid Chromatography (HPLC)
  • Gas Chromatography (GC)
  • Atomic Absorption Spectrophotometry (AAS)
  • Inductively Coupled Plasma Mass Spectrometry
  • Molecular Biology
  • Mammalian Cell Culture
  • In Vitro Fertilisation (IVF)

To achieve the required quality, the water undergoes very high levels of purification to remove contaminants and impurities such as:

Dissolved organics (e.g. Pesticides), Dissolved Inorganics (e.g. Iron, Copper, Lead), Bacterial Endotoxins, Suspended particles and colloids,
Trace Ions (E.g. Silica & Boron), Nucleases (RNase & DNase), Bacteria (<0.1 CFU/ml)
