All EASYpure II Models feature a compact design that allows ultrapure water to be placed within easy access of your point of use. Microprocessor-controlled purity monitor provides digital resistivity readings, temperature compensated to 25°. A standby mode recirculates the purified water for 10 minutes every hour of inactivity. Water remains clean and free from recontamination and ready to use when you need it! All components are constructed of extremely inert materials ensuring maximum ionic and organic purity. All units except the EASYpure II RF and RF/UV come complete with a wall bracket providing more flexibility in choosing a location. Each system produces water that exceeds all ASTM, NCCLS and CAP Type I water standards. Ideal for laboratories requiring < 15 liters per day of high quality water. Several cartridge types are available allowing you to adapt to your specific feed water source and application. Incorporates a 0.2-micron hollow fiber absolute filter providing water free of particles and bacteria. Whisper quiet pump provides optimal flow rates and silent operation. Ideal for analytical procedure requiring water that is free of organics, inorganics and bacteria. Delivers 0.8 liters of ultrapure water per minute. All units except come complete with a wall bracket providing more flexibility in choosing a location. Feed water must be pretreated by reverse osmosis, distillation or deionization. The EASYpure II RF and RF/UV systems feature an integral noncontaminating feed water reservoir that store up to 6.5 liters of water. Simply pour pretreated water into the easily accessible reservoir. Ideal for your most demanding applications including, HPLC, GFAA, TOC, GC/MS and ICP; MS and IC. Portable, reservoir feed systems requires no piping or special installation. A good choice for work areas where direct plumbing is not available. Allows ultrapure water to be placed within easy access of analytical instruments. The RF system: provides less than 5 ppb Total Organic Carbon and up to 18.2 megohm-cm water. The RF/UV system: provides 1-5 ppb Total Organic Carbon and up to 18.2 megohm-cm water. 100-240 VAC.
