Barnstead GenPure xCAD Plus Ultrapure Water Purification Systems by Thermo Scientific

• Ultraviolet (UV) Oxidation effectively prevents bacterial contamination and oxidizes organics to produce pure water with low TOC levels; prevents risk of false TOC value as a result of diminished UV intensity; combination of 185/254 nm oxidizes organic compounds and allows for total oxidizable carbon levels of less than 5 ppb ideal for applications requiring extremely low levels of organics
• Ultrafiltration (UF) removes molecules (pyrogens, nucleases, microorganisms and particulates) above their rated size; ideal for tissue culture, cell culture and media separation
• Combination of Ultraviolet Oxidation and Ultrafiltration (UV/UF) produces water virtually free of all impurities; removes nucleases such as RNase and DNase and pyrogens; produces water with low TOC and pyrogen levels
• Online Total Organic Carbon (TOC) with UV Intensity monitors real-time continual measurement of organic substances present in the water; continuously monitors UV intensity and removes risk of false TOC values caused by diminished UV intensity; alerts user when UV lamp is insufficient for accurate TOC measurements
• All models exceed international standards ASTM Type I, ISO 3696 Grade 1, ASTM D1193 and CLSI-CLRW
• Bench and wall mount models include mounting bracket up to 8 ft. (2.5 m) from main unit; bench models can be mounted under bench
• Electronic dosing with automatic volume control of 0.01-65 L with <2% accuracy
• Integrated feed water monitoring measures water conductivity with measuring cell and immediately displays fault message if quality of feed water drops below set value
• Conductivity cells carefully calibrated before each measurement with built-in reference resistance with cell constants at 0.01 cm-; platinum chip sensor measures temperature with ± 0.1°C accuracy
• Aquastop quick connect allows cartridge replacement within seconds between uses and in mid-operation; one part number ordering
• Suitable for applications requiring Type 1 ultrapure water: life sciences and analytical chemistry
• Ergonomic design with tilting display and swivel arm
• Models are ready to use

GLP-compliant documentation

• Operating system protected by real-time clock and code prevents unauthorized changes to system settings
• Safe data transfer of all measured data, faults, date and time to a PC computer or log printer with RS-232 interface with adjustable send
• Digital microprocessor control automatically monitors and stores faults from last four weeks
• On and off switch for USP-compliant conductivity measurement with temperature compensation
