Model: 2121BL - Biological Grade Ultra-Low TOC Type I DI System

The system produces 18.2 megohm-cm ultrapure, reagent grade water that is free of pyrogen, endotoxin, RNase and DNase at a flow rate of 2-Liters/minute. A built-in dual wavelength UV Oxidizer/Sterilizer reduces TOC levels to & 5 PPB, prevents the growth of microorganisms within the system, and alerts you when it is time to change the lamp. Continuous recirculation is utilized to maintain maximum water purity. Therefore, ultrapure water is instantly available on demand up to 7 feet from the system via the provided hand held remote dispenser. The digital Conductivity/Resistivity monitor displays the water quality and a Green LED indicates that the water quality is above the acceptable purity. When the water quality drops below the desired purity, a Red LED alerts the user that it is time to replace the filters.

This affordable lab water system is simple to install and easy to maintain. The system cabinet can be bench, shelf or wall mounted without the use of costly wall mounting brackets. It has a 2-year warranty in most countries and is proudly made in the USA.

A High Flow/High Capacity (8-12 Liters/Min) version of this system is also available (Model: 2035BL).

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.
