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

TYPE 2 WATER 


 What is Type 2 Water?

The water type defines the water specification regarding the level of contaminants such as organics, ions, pyrogens and bacteria.

Type 2 water is water that has undergone a general level of purification in order to meet lab water purity requirements. Type 2 water has a resistivity level of up to 10 MΩ-cm.

Type 2 water, also known as Pure Water, is typically used for general lab applications that do not require a higher level of water purity (Type 1) including:

  • Histology
  • Titrations
  • Stability Tests
  • General Chemistry
  • Feed to Type 1 Systems
  • Stainless Steel Autoclaves
  • Nitrogen-phosphorous (NP) Analyzers, PH solutions
  • Biochemical Oxygen Demand/ Chemical Oxygen

TYPE 2+ WATER 


How is Type 2+ Water Different to Type 2?

Type 2+ water is used for general laboratory applications which require a higher inorganic purity than Type 2 water. Type 2+ offers a resistivity level of up to 15 MΩ-cm through full recirculation and also includes a UV, which most Type 2 systems do not have.

Type 2+ water is used where the application requires a higher inorganic and ionic purity than standard Type 2 water. Type 2+ may be used for applications such as:
  • Electrochemistry
  • Dissolution Testing
  • Surface Tension Experiments
  • Spectrophotometry
  • Particle Analyzers

Type 2 and 2+ water undergoes a general level of lab water purification to remove contaminants and impurities such as: 

Organics (e.g. Pesticides), Inorganics ( e.g. Iron, Lead, Copper), Bacteria
(<5 CFU/ml), Particulates (>99.9% Removal of up to 0.2µm)
