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:
- 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.
- Dissolution Testing
- Surface Tension Experiments
- 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)
