A successful water system design begins with a clear and precise definition of user needs throughout the facility. The purity level and volume of water required at each point of use can vary considerably and therefore must be fully assessed in order to properly inform the designer of the water purification system.
Top 4 Questions You Should Ask When Buying a lab water purification system
1. What do you need the water for? What is your application? 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? The budget 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, does it need to be validated?
