At NJ Labs, we ensure the highest quality standards across all testing operations—including the water we use in our laboratory processes. Our Milli-Q® Integral 5 Purified Water System from Millipore delivers ultrapure, reagent-grade water that supports high-sensitivity chemical and microbiological analyses, ensuring consistent and accurate results in every test.
This advanced water purification system is a critical component of our Good Laboratory Practices (GLP) and CGMP-compliant testing protocols, supporting applications from wet chemistry and HPLC to ICP-MS and microbiology.

The quality of water used in analytical procedures directly impacts test reliability, especially in trace-level testing such as:
Impurities like organic compounds, ions, particulates, or bacteria in water can introduce background noise, false positives, or contamination. That’s why NJ Labs uses the Milli-Q® Integral 5—a trusted system designed for consistent water production.
The Milli-Q® Integral 5 is a fully integrated, point-of-use ultrapure water purification system. It combines reverse osmosis (RO), UV photo-oxidation, ion exchange, and 0.22 μm final filtration to ensure the highest quality of water for critical lab use.
We use ultrapure water from the Milli-Q® Integral 5 system in:
Our use of the Milli-Q® Integral 5 is part of our broader commitment to data accuracy, regulatory compliance, and scientific integrity. With every test we perform, clients can trust that the supporting systems—including water quality—are optimized to meet the most demanding industry standards.
When you partner with NJ Labs, you’re getting more than just results—you’re getting precision built on decades of experience, powered by high-quality systems like the Milli-Q® Integral 5.
