Water Purification

Water Purification

Every laboratory requires purified water. Every application requires a specific grade of purified water. 

Determining which ‘grade’, ‘quality’, ‘type’ or ‘technology’ your laboratory needs, is not always easy. Here at Avidity Science, we are proud to have a team of experts available to guide you to the right solution; we have a system or can design a combination, for your bespoke requirements.

What is the Relevance of Water Purification?

Reagent quality is critical to the accuracy and repeatability of results. Ultimately the success of laboratory or clinical endeavours depends on the quality, accessibility and reliability of the pure water supply.

Understanding Water Purification

In order to produce pure water suitable for use in scientific applications, water must pass through a series of technologies which remove impurities. Various laboratory applications require the removal of different impurities and therefore a range of technologies are utilised.
