Perfect for Diverse Laboratory Applications

The PURELAB® Flex 3 System is excellent for various laboratory uses. This system can produce water ranging from RO Type III to ultrapure Type I, making it suitable for:

What is Real-Time TOC Monitoring and How Does It Work?

Real-Time TOC Monitoring means continuously (live) measuring the amount of Total Organic Carbon (TOC) present in water, providing instant data without any delay.

TOC refers to those carbon compounds that indicate organic contaminants, such as bacteria, dead cells, or organic chemicals.

In advanced systems like the ELGA PURELAB Flex 3, there is a UV oxidation sensor that breaks down organic compounds in the water and measures their TOC levels.

This process is automated and continuous, so the lab always knows the current purity level of the water. Real-time TOC monitoring reduces the risk of contamination and increases trust in water quality for high-precision experiments.

Advanced Purification Technology

Real-Time TOC Monitoring

One of the standout features of the PURELAB® Flex 3 System is its real-time Total Organic Carbon (TOC) monitoring capability.

This continuous monitoring ensures that water purity remains consistent throughout your operations, providing reliable quality assurance for sensitive applications where even minor contamination could compromise results.

Type I Ultrapure Water Production

The system delivers ultrapure Type I water with a resistivity of 18.2 MΩ-cm, meeting the most stringent requirements for laboratory applications.

This exceptional level of purity is essential for sensitive analytical techniques and critical life science research where water quality directly impacts experimental outcomes.
