Polish pretreated water with the Milli-Q Academic to produce up to 1.5L/min. ultrapure reagent-grade Type I water with 18.2 megohm·cm resistivity and <10ppb TOC. Will meet or exceed ASTM Type I Standard Specifications for Reagent Grade Water.
The standard academic model employs a 3 step purification process.
Choice of continuous or intermittent water circulation maintains water purity when system is not in use
Point-of-use dispenser with ergonomic trigger delivers water continuously or at fixed volumes from 8 oz. to 17 gal. (0.25 to 64.5L) in 8 oz. (0.25L) increments
Backlit LED displays system parameters in six languages (English, Spanish, French, German, Italian and Japanese)
Setpoint alarm activates if system malfunctions
Systems can be bench-, wall- or underbench-mounted
FLOWRATE: up to 1.5L/min
PARTICLES: <1/ml (particle size: > 0.22 um)
TOC: 5-10ppb ppb (this specification came from test conditions where a Milli-Q Gradient was fitted with a Q-GardR 1 Purification Pack and a Quantum. EX Ultrapure Cartridge and the feedwater came from a Millipore RiOs Water System) The feedwater TOC value was < 50 ppb). The TOC of the Milli-Q Product Water can vary as a function of the feedwater TOC.
MICRO-ORGANISMS: <1 CFU/ml
