2017 Water Purification Survey Results

Get questions to ask when purchasing, plus the results of our 2017 survey.

Erica Tennenhouse, PhD

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 4 Questions You Should Ask When Buying a Water Purification System

  1. What do you need the water for? What is your application and what type of water is needed? What is the source of your current water? How much water is required per batch/day? Are there special requirements for delivery?
  2. What is your budget? (This will determine the technology). What is the cost of ownership over five years?
  3. 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?
  4. 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?
