Water purification systems remove contaminants from feed water, including inorganic ions, organics, colloids, gasses, bacteria, and proteases to ensure accurate results, cleaning, preventing mineral buildup, and more. Depending on your applications and the space you have in your lab, there are many different filtration types, water purification techniques, and system configurations that could work best.

6 Questions to Ask When Buying a Water Purification System:

  1. What level of purification do you need?
  2. How much water will you require at one time?
  3. How often do filters and cartridges need to be replaced?
  4. How long does it take for the unit to purify the water?
  5. Where will the system be located, and do you have enough space?
  6. Can the system be expanded if demand increases?

Sustainable Water Purification

Collecting the ultrapure water that many lab applications require can consume a lot of energy and resources. However, it’s possible to optimize your lab’s water purification processes and minimize environmental impact, such as by maintaining purifiers properly to maximize lifespan and making greener purchasing decisions upfront.
