Model: 2122BL - Ultra-Low TOC Biological Grade

The AQUA SOLUTIONS' Model 2122BL is also available in a High Flow/Capacity (4-10 Liters/Min) version. These laboratory water purification systems are semi-custom designed for each application. Contact your salesperson for more information.

This unit operates on ordinary tapwater. For pre-treated tapwater operations, see Model: 2121BL. Other available versions of this unit include built-in reverse osmosis pre-treatment in a single cabinet design measuring just 20" wide x 20" high x 12" deep (Model: RODI-C-12BL).

This system is available with or without an additional built-in ultraviolet (UV) sterilizer to further control the growth of microorganisms within the system.

This system produces 18.2 Megohm-cm type I ultrapure, reagent grade water that is free of Pyrogen, Endotoxin, RNase and DNase at a flow rate of 8-12 Liters/minute. The unit is ulitized in operations using pretreated feed water that contains less than 20 PPM of total dissolved solids. This laboratory water purification system includes a built-in 5,000 MWCO ultrafilter cartridge and a built-in dualwavelength UV Oxidizer/Sterilizer that reduces TOC levels to < 5 PPB, for microorganism growth prevention within the system.

More Information

All AQUA SOLUTIONS Biological Grade Type I DI Laboratory Water Purification Systems produce purified water that meets or exceeds ASTM, CAP and CLSI specifications for Type I reagent grade water. Since ordinary tap water contains 5-25 times the impurities of pretreated water, these tap water systems have lower overall capacity than pre-treated water systems.
