Model: 2035BU - Biological Grade Type I DI System

This AQUA SOLUTIONS unit operates on pre-treated tapwater. For ordinary water operations, see (Model: 2036B).

Laboratory water purification systems are also available with a built-in Dual wavelength UV Oxidizer/Sterilizer (Model: 2035BL).

The Purification Kit Number 2635M1T is required to ensure optimal performance of this laboratory water purification 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 operates on pre-treated feed water that contains less than 20 PPM of total dissolved solids. This laboratory water purification system also includes a built-in 5,000 MWCO ultrafilter cartridge.

The built-in UV Sterilizer prevents the growth of microorganisms within the system and alerts you when it is time to change the UV lamp.
