Merck Millipore has introduced two types of bottled water with certified water quality: water for cell culture and water for molecular biology.
The waters are produced in an ISO 9001/CGMP environment and are subject to strict quality control tests.
The two types of water are intended for research use by scientists performing critical cell culture or molecular biology experiments.
Both water types are sterile.
In addition, water for cell culture is cell-culture tested and free of pyrogens, mycoplasma, calcium and magnesium.
Water for molecular biology is RT-PCR tested and is RNase-free, DNase-free, protease-free, calcium-free and magnesium-free.
A proprietary Merck Millipore process is used to manufacture the bottled water, according to lab water group product manager, Jean-Francois Pilette.
He said: 'We're able to produce high-quality ultra-pure water without the need for toxic chemicals such as diethylpyrocarbonate (DEPC).
'Following the purification process, the ultrapure water is aseptically filled into sterile PET containers.
'We expect researchers who need small volumes of ultrapure water for their cell culture or molecular biology work to fully benefit from the new products,' Pilette added.
For easy traceability, bottles are delivered with duplicate labels, allowing one to be removed and kept in a lab notebook for future reference concerning water quality and lot numbers in experiments.
A space on the label is provided for handwritten entry of the opening date by the researcher.
The bottled water is available in a range of volumes (1 litre, 0.5 litre and 125ml) and packaging options to match researchers' needs.
