Laboratory Ultrapure Water System


The Crystal EX Ultrapure systems are economy class, multi-purpose, water purification systems.

All Crystal EX Systems produce two types of water : Ultrapure (ISO 3696 Grade 1) and Pure (ISO 3696 Grade 2). Ultrapure water produced by the Crystal EX systems has resistivity 18.2 Mega Ohm*cm (conductivity 0.055 μS/cm). This exceeds requirements of all the relevent standards (ISO 3696 Grade 1, ASTM Type I, CLSI Type I). Purified water is collected in a storage tank. The recirculation system ensures a consistent quality of water, and a low level of organic carbon content (TOC). TOC is <2 ppb for "HPLC" and "Bio" configurations, and 5-10 ppb for the "Trace" configuration.

The dispensing rate of high quality Ultrapure water is 2 L/min.

Pure water produced by Crystal EX systems can be used for labware washing, wet chemistry methods, flame spectrophotometers, etc., Pure water is dispensed directly from the storage tank. The dispensing flow rate of pure water is 4 L/min.

Crystal EX Ultrapure water systems are available in the following configurations: :

  • Crystal EX Trace System (P/N EX-1001-P) produces water for inorganic trace analysis. This water is recommended for atomic absorption spectrometry (with graphite furnace atomizer), ICPOES analysis, ICP-MS and other inorganic analytical methods.
  • Crystal EX HPLC System (P/N EX-1101-P) produces water with very low organic carbon content (TOC) to comply with the requirements of liquid chromotography methods. Crystal E HPLC water can also be used for some microbiological and molecular biology applications
  • Crystal EX Bio System (P/N EX-1201-P) produces water with very low organic and RNase / DNase content, intended for molecular biology, including RNase - sensitive applications.
