Line fed basic system can be found here
Compact system for requirements of less than 15L of pure water per day.
Choose portable batch feed system, line feed system, UV line feed system or UF line feed system. Uses feed water pretreated by reverse osmosis, distillation or deionization. Microprocessor controlled purity monitor provides digital resistivity readings, temperature compensated to 25 deg. C. In standby mode, water circulates for 10 minutes every hour to maintain purity.
Batch feed model features a 7L polypropylene filtered storage reservoir, low water pump protection and a 0.5L per minute flow rate.
Line feed model is fed from a pressurized feed line or a gravity feed storage tank and has up to 1.5L per minute flow rate. Both models produce Type I water with total organic carbon content less than 10 ppb.
UV line feed model features dual wavelength ultraviolet light 185 and 254nm to provide water purity of below 3 ppb TOC and up to 18.3 megohm-cm; 0.2 micron filter removes particles and bacteria at outlet.
UF line feed model uses a 10K mol wt. ultrafilter to provide less than 0.005EU/ml pyrogen levels and greater than 4 log reduction of pyrogens.
All models have cabinet with metal back and molded plastic front and can be either bench or wall mounted.
Size: 121/4Wx183/4Dx181/8H inch.
Batch feed model uses two cartridges;
line feed, UV line feed and UF line feed models require three cartridges.
Type I. For applications requiring less than 4 gal./day 15L/day of ultrapure water. Provides affordable and convenient alternative to bottled water. Six application-specific models meet most critical analytical, biological or life science needs. Ultrapure water is dispensed directly from the system, eliminating cross-contamination that may occur with use of large containers or bottled water.
Provide 3/4 pt./min. 0.8L/min. flowrate. No permanent supply of water required; unit can be placed virtually anywhere in laboratory. Integral 3/4 gal. 6.5L reservoir is filled with pretreated water - RO, distilled, or DI and is used to feed cartridges. Model RF/UF uses integral dual wavelength 184 and 254nm UV lamp that provides for organic-free water and bacterial control within the system. Digital resistivity monitor measures system purity. Optional remote dispenser 09-035-15 delivers water up to 8 ft. from system. All systems produce Type I water with resistivity of 18.2 megohm·cm and TOC Total Organic Carbon levels as low as 1 ppb . Ideal for applications such as AA, HPLC, TOC, GC and GC/MS, Ion Chromatography, ICP/MS and and where RNase-free water is required for critical amplification techniques.
