Model: 2122AU - Analytical Grade Type I DI System with UV Sterilizer

This affordable lab water system is for use on tap water and produces 18.2 megohm-cm ultrapure, reagent grade water at a flow rate of 2-Liters/minute. A built-in UV Sterilizer prevents the growth of microorganisms within the system and alerts you when it is time to change the lamp. Continuous circulation is utilized to maintain maximum water purity. Therefore, ultrapure water is instantly available on demand up to 7 feet from the system via the included hand held remote dispenser. Water quality is monitored by a temperature-compensated Conductivity/Resistivity meter with a digital display. The meter has a Green LED to indicate 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.

The system is simple to install and easy to maintain. The 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: 2036AU).

Operating costs for this system are dependent on feed water quality and usage. If the tap water used contains more than 170-200 PPM total dissolved solids and/or usage exceeds 15-20 liters per week, then an RODI systems with built-in RO pre-treatment will save you money by lowering operating costs (see Model: RODI-C-12AU).
