High-purity central lab water refers to water that has undergone extensive purification to remove impurities and contaminants, making it suitable for use in laboratory applications. In scientific research, analytical testing, and various laboratory procedures, the quality and purity of water are crucial to ensure accurate and reliable results.
The process of obtaining high-purity lab water typically involves multiple purification methods to achieve the desired level of cleanliness. Some common purification techniques include:
1. **Reverse Osmosis (RO)**: This process involves passing water through a semi-permeable membrane to remove a wide range of impurities, including ions, bacteria, and large molecules.
2. **Deionization (DI)**: Also known as demineralization, this method uses ion-exchange resins to remove charged ions from the water, further reducing its conductivity and mineral content.
3. **Ultrafiltration**: This filtration method utilizes membranes with very small pores to remove particulate matter, colloids, and macromolecules.
4. **UV (Ultraviolet) Treatment**: UV light is used to disinfect the water by inactivating microorganisms such as bacteria and viruses.
5. **Electrodeionization (EDI)**: This process combines ion-exchange resins with electrochemical regeneration to achieve high-purity water continuously.
By combining these methods, laboratory-grade water can reach high levels of purity, usually expressed in resistivity or conductivity units. The most common unit used to measure the purity of lab water is megohm-cm (megaohm per centimeter) or microsiemens per centimeter (μS/cm). For example, ultrapure water may have resistivity values exceeding 18.2 megohm-cm or conductivity values below 0.055 μS/cm.
High-purity central lab water is used in a wide range of laboratory applications, such as preparing reagents, diluting samples, running analytical instruments (e.g., HPLC, GC-MS), and performing cell culture work. It ensures that the water itself does not introduce any unwanted variables that could affect the accuracy and reproducibility of experiments.
The distribution of this water is equally important, to meet flow and pressure specs, while maintaining biological levels below specs which are often quite stringent. Let us help you with a standard or customized solution to meet your needs.
