Laboratory water purification systems are a common fixture in a variety of different types of facilities. In order of decreasing purity, the different classifications of pure water are as follows: Type 1, Type 2, and Type 3. Type 2 water is used for tasks such as buffer preparation, clinical laboratory analyzers, and culture media and is also used as feedstock for Type 1 water. Type 3 water, on the other hand is used for cooling and heating devices to avoid problems with mineral deposits from circulating water and is also utilized for washing and rinsing labware. There are a variety of water purification techniques with the most common including ultraviolet oxidation, adsorption, reverse osmosis, electrodeionization, deionization, filtration, and distillation. Some things you should consider if you are looking to buy a water purification system are: what are you using the water for, what type of water you need, and how much water you need. You will also want to ask the vendor what the cost of the system will be over five years and what kind of service and/or warranty is provided. Space is another important consideration in the purchasing process.

• Rinsing and washing labware
• Buffer preparation and clinical laboratory analyzers
• Culture media
• Testing for contaminants in drug samples
• Molecular biology and cell culture work
• GC, HPLC, UHPLC, AA, ICP-MS and other advanced analytical techniques
