Some laboratories have small daily water volume requirements that can be met with individual point-of-use pure water systems. Other laboratories requiring larger volumes of pure water today have the option of choosing from centralized or stand-alone water purification systems. In some cases, both types of systems may be present in a facility in order to meet scientists' specific needs.
In situations where RO water is delivered to multiple laboratories in a central “loop” configuration, end-users sometimes find that it is preferable to change to an installation that provides them with greater control over the quality of the water produced for use with their applications. This can be done quite easily by discontinuing use of the RO centralized water supply, and introducing one or more Elix Advantage systems to produce pure water directly from tap water. The pure water produced by the Elix systems can then be used for all a lab's pure water needs, including the production of feed water for Milli-Q ultrapure water purification systems.
