Barnstead Nanopure Diamond – Analytical Water Purification System

The Barnstead Nanopure Diamond is a trusted ultrapure water purification system designed to meet the most demanding laboratory requirements. Delivering ASTM, ISO 3696, CAP, NCCLS, and CLSI-CLRW Type I water, it provides up to 15 liters of ultrapure water per day through a four-stage purification process that combines pretreatment, UV oxidation, ultrafiltration, and a final 0.2 µm filtration step. Real-time resistivity and conductivity monitoring ensure consistent water purity, making it an indispensable solution for analytical, pharmaceutical, and life science laboratories where precision is critical.

At HiTechTrader, we make advanced water purification systems like the Barnstead Nanopure Diamond more accessible by offering refurbished and pre-owned units. Each system is fully inspected, serviced, and tested to guarantee reliable performance, providing laboratories with a cost-effective way to secure ultrapure water without compromising on quality or compliance.
