6 Questions You Should Ask Before Buying a Water Purification System

Find out the most sought-after features and more from the latest water purification survey results

By Shane Downie

Water is the most commonly used laboratory reagent; however, the importance of water quality is often overlooked. Because impurities can be a critical factor in many research experiments, water purity ranks high in importance. There are several types of impurities and contaminants in water such as particulates, organics, inorganics, microorganisms, and pyrogens that can adversely affect results.

Top 6 Questions You Should Ask When Buying a Water Purification System

  1. What is your application and what type of water is needed? Type I, II, or III? Will you require ultra-low TOC lab water?
  2. What is your expected volume usage? How much is required per batch/day?
  3. What is the source of your current water? Are there special requirements for delivery?
  4. What is your budget? (This will determine the technology). What is the cost of ownership over five years?
  5. Where do you need the system in the lab(s)? Consider: top of counter, under counter or wall mounting the unit. What is the overall footprint/real estate of the system(s) and components?
  6. What kind of warranty and service is provided? Is the system manufactured to quality standards and which ones? Is this a pharmaceutical application that needs to be validated?
