Model: 2035BL - Biological Grade Type I DI System

This AQUA SOLUTIONS unit operates on pretreated water. For ordinary tapwater operations, see Model: 2036B

Laboratory water purification systems are also available with a built-in sterilizer (Model: 2035BU) or 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 is utilized in operations involving pretreated feed water that contains less than 20 PPM of total dissolved solids. It includes a built-in 5,000 MWCO ultrafilter cartridge and a cabinet that can be bench, shelf or wall-mounted at no extra charge.
