Laboratory Water Purification Systems
Lab water can be complicated but the equipment you use to produce it shouldn’t be! That is why LabStrong™ is devoted to developing cutting-edge equipment and products that are easy to install, use and maintain.
What is lab water?
Water plays a crucial role in the laboratory. The types of applications being performed will determine the purity of water that is needed, some labs may need multiple types of water. ASTM International (formerly known as American Society for Testing and Materials) defines laboratory grade water into four categories: Type I, II, III and IV. A brief summary of the types of water is below.
Type I – Ultrapure
- Resistivity of >18 MΩ-cm at 25°C
- TOC (total organic carbons) <50 ppb
- Needed for critical lab functions
- Used for tissue and cell cultures and DNA research (pharmaceutical research)
- Required for ultra-sensitive analytical instruments
- Achieved through deionization, all ions are removed but may still contain small amounts of organics, endotoxins and nucleases. Additional processes are needed to achieve type I plus water. With an ultraviolet light, any remaining bacteria and organics are removed. If DNase and RNase need removal, a combination of an ultraviolet (UV) light and ultrafilter (UF) will be required.
Type II – Pure
- Resistivity of ≥1 MΩ-cm at 25°C
- TOC (total organic carbons) <50 ppb
- Needed for basic lab functions
- Can be used as a pretreatment to an Type I ultrapure water system
- Used for creating buffers and media production, general chemistry and spectrophotometry
- Commonly produce through deionization or distillation. Deionization will remove mineral ions. Distillation is known to remove a wider range of impurities than any other purification process and can remove inorganic ions, dissolved gases, organics, particles, bacteria and pyrogens.
Type III – Primary Grade Water
- Resistivity ≥ 4 MΩ cm at 25°C
- TOC (total organic carbons) <200 ppb
- Needed for non-critical laboratory functions
- Can be used as a pretreatment to a Type II pure or Type I ultrapure water system
- Typically produced through reverse osmosis (RO) plus ion exchange or EDI and removes inorganic solids, organics, particles and microorganisms.
What type of water do you need?
Type IV - Feed
- Resistivity ≥ 0.2 MΩ cm at 25°C
- No limit to TOC (total organic carbons) content
- Typically produced by RO, distillation or other methods and is used as a feed water to a water purification system.
- Contaminants typically found in this type of water are dissolved ions, minerals, microorganisms and organic compounds
