The Right Choice For Water Purification Systems
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.
ELGA PURELAB flex 3 & 4
The PURELAB flex 3 & 4 are the latest additions to the award-winning PURELAB flex range of water purification systems. The PURELAB flex offers many advantages for analytical and lifescience applications. It allows users to focus on routine test work, without having to worry about the water 
quality affecting any test results.
• Ensure accurate, consistent results
• Both systems deliver up to 10 liters of ultrapure water per day and up to 2 liters per minute
• The flex 3 delivers ultrapure water direct from potable tap water and the flex 4 requires a pre-purified feed

• Features speed rotation range of 5 to 280 rpm
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.
