The PURIST® Ultrapure Water System produces ultrapure water from EDI, reverse osmosis (RO), distilled or deionized water. 
• Automatic system recirculation every hour to prevent bacteria from growing inside the system 
• A dual UV lamp to kill bacteria and reduce organics to trace level 
• Volumetric dispensing and calibration 
• Alarm and maintenance info on a large color LCD monitor
• Adaptable to various final filters.(e.g., final filters for HPLC or to remove RNAse/ Endotoxins)
• Real-time Resistivity measurement by a high-precision resistivity meter with temperature compensation (conductivity cell constant 0.01cm -1) 
• Small compact footprint that occupies minimal space in your lab 
• Ergonomically designed to ensure a simple installation, operation and easy maintenance 
• Manufacturing plant is ISO9001:2008 certified 
Main Applications:
• Preparation/dilution of HPLC mobile phases, blanks, sample and buffers in GC, HPLC, AA, ICP-MS and other advanced analytical techniques.
• Preparation of media for mammalian cell culture, IVF, reagents for molecular biology applications.
