In the lab, much time and effort are spent designing and planning experiments, selecting reagents, etc. But how often do scientists pause to ensure they’re working with the correct water quality for their analyses? Daniel Darbouret is a Senior Scientific Director who has been working with Milli-Q® Lab Water Solutions portfolio for over 30 years. In this episode, Daniel explains why purified water is critical to scientists in the lab. He looks at why not all water is purified to the same extent, and defines which water quality scientists need for which analyses. In our Troubled Waters segment, Estelle Riché, Applications Expert, tells us why it’s so difficult to measure the pH of ultrapure water and gives us a better way to assess its quality.
