Water, water, everywhere…

August is National Water Quality Month, and what better time to promote the benefits of pure water.  Water is essential to all living things, and a vital component in research laboratories.  We all know we should drink about eight 8-ounce glasses of water per day.  But, we should also ensure we have plenty of purified water in our laboratories for testing.  Tap water may be safe for drinking, but for complex laboratory procedures, tap water must be purified even further.

Impure water will dramatically affect your ability to obtain accurate results in the laboratory.  Pure water is essential in the modern laboratory for a vast number of applications including reagent preparation, high-purity rinsing, Atomic Absorption (AA), mass spectroscopy, chromatography, monoclonal antibody production, gel electrophoresis, and much more.

Thermo Scientific Barnstead EASYPure® RODI

Cole-Parmer offers all the tools you need to ensure you have pure water in your laboratory, suitable for all your research needs.  Our  Thermo Scientific Barnstead EASYPure® RoDi produces water that exceeds ASTM & NCCLS Type 1 standards with resistivity up to 18.2 megohm-cm and < 5 parts per billion (ppb) Total Organic Carbon.  These systems are compact, and may be placed anywhere in your lab, and quickly and effectively purify your tap water.  The RoDi is the ideal system for < 15 liters per day for your most sensitive analytical procedures.  The system re-circulates water between the reservoir, the purification cartridges, and theUV lamp to ensure Type 1 water is continually available. Pre-treatment filter and reverse osmosis membrane initially improve water quality, while deionization, UV light, and a 0.2 micron final filter provides final polishing, organic oxidation, and removal of micro-particulates and bacteria.

For the research scientist, without purified water, Samuel Taylor Coleridge’s poem The Rime of the Ancient Mariner could have another meaning, perhaps

Water, water, everywhere,

Nor any drop for reagent preparation.

Well, we’ll stick to laboratory supplies, and leave the poetry to the professionals!
