This 'two in one' lab water system produces ultrapure (Type I) and RO (Type III) water from tap water. Quality of ultrapure water meets or exceeds ASTM, CLSI, CAP, and ISO Type I water standards.
The graphic display guides users through system operation, performance, troubleshooting and maintenance, and can be password protected for multiple access levels. Applications (Type I - ultrapure water): HPLC mobile phase preparation; preparation of reagent blank solutions; sample diluent for GC, HPLC, ICP-MS, AA and other analytical techniques; preparation of buffers and culture media for mammalian cell culture; preparation of molecular biology reagents. Applications (Type III - RO water): Glassware cleaning, washing machines for glassware, water bath water, autoclave filling, water for laboratory animals. Certifications: The VWR® water system is delivered with a Certificate of Conformity ensuring that it has been built and tested fully assembled following Standard Operating Procedures, and a Certificate of Calibration for the temperature and resistivity meters built into the system. Consumables are automatically delivered with a Certificate of Quality. Manufacturing site is ISO 9001 (2015) and ISO 140001 certified. |
