Thermo Fisher Scientific Announces New Water Quality Specifications

Thermo Scientific Barnstead Nanopure Water Purification Systems Exceed Industry Standards

MILFORD, Mass. (March 15, 2010) - Thermo Fisher Scientific, the world leader in serving science, today announced new water quality specifications for the Thermo Scientific Nanopure Life Science water purification system. Thermo Fisher evaluated the system to see how well it cleared bacteria, pyrogens and nucleases from a sample using highly sensitive testing protocols. The results indicate that Nanopure-purified water can be used in scientific applications that are most sensitive to these impurities. Customers who traditionally purchase nuclease-free bottled water or who treat water with DEPC (Diethylpyrocarbonate) will benefit from the efficiencies of having an on-demand source of nuclease-free water.

Thermo Fisher tested the bacteria and pyrogen levels in conjunction with Nelson Laboratory of, Salt Lake City. The testers found that the pyrogen level in the Nanopure water was <0.001 EU/ml, and the bacteria level was <0.01 CFU/ml. Thermo Scientific Genomics in Milwaukee, Wis. tested for the presence of nucleases, and the testers found that RNase level was <0.003 ng/ml and the DNase level was <0.4 pg/µl. All measurements exceeded current industry standards.

Customers who require pyrogen and nuclease-free water can use the Nanopure Life Science unit to produce ultrapure water on demand. The system utilizes an ultrafilter to clear these biological impurities from the water. The integration of the ultrafilter into the main water flow of the system enables continuous rinsing of the filter and provides additional protection from potential contamination for a life-span of up to two years. This cost-effective pure water system produces extremely high-quality nuclease-free and pyrogen-free water.
