Deionized water, also referred to as DI water or grade 1, is water that has been purified of virtually of its mineral ions through the use of uniquely manufactured ion-exchange filters in accordance with ASTM D1193. In some cases, this method may be used in combination with reverse osmosis (RO) to raise the level of purity. There are different types of deionization processes which are determined primarily by the type of resin used – cation or anion. Deionized water systems play key roles in numerous forms of laboratory testing as well as in industries such as food processing, pharmaceuticals, and manufacturing. The type and scale of the system can vary significantly depending on the desired applications.

| Description | AQUA SOLUTIONS' Ultra-Low TOC Biological Grade Type I DI Systems are available in Standard (2-3 Liters/Min) and High Flow/Capacity (4-10 liters/min) versions, for operation on either Ordinary Tap Water or Pretreated Water. All AQUA SOLUTIONS' Ultra-Low TOC Biological Grade Type I DI Systems produce AQUA SOLUTIONS' Ultra-Low TOC Biological Grade Type I DI Systems are available in Standard (2-3 Liters/Min) and High Flow/Capacity (4-10 liters/min) versions, for operation on either Ordinary Tap Water or Pretreated Water. All AQUA SOLUTIONS' Ultra-Low TOC Biological Grade Type I DI Systems produce purified water that meets or exceeds ASTM, CAP and NCCLS specifications for Type I reagent grade water. Ultra-Low TOC Biological Grade Type I DI Systems include a built-in dual-wavelength ultraviolet (UV) oxidizer/sterilizer to reduce TOC the lowest possible levels, and a built-in ultrafilter (UF) to reduce pyrogen, endotoxin, RNase and DNase. This combination of UV-UF also results in water that has no RNase or DNase activity.
Features
- Built-in 5,000 MWCO ultrafilter (UF) module
- Built-in combination ultraviolet (UV) oxidizer/sterilizer
- Continuous recirculation ensures superior water quality at all times
- Highest flow rate (2-3 Liters per Minute) of any comparably sized system
- Highest ion exchange capacity (4,000 grains) of any comparable system
- Built-in activated carbon prefilter reduces particulates & organics for longer DI module life
- Digital, temp-compensated resistivity monitor with red/green LED alarm set point
- Teflon recirculating remote dispenser with 0.10 µm final filter capsule
- System can be bench, shelf or wall-mounted at no extra charge
- Two (2) year system warranty (US & Canada only)

- Continuous recirculation is utilized to ensure water quality and prevent the growth of microorganisms within the system.
- Made in the USA.
- Includes LCD readout conductivity monitor with adjustable setpoint and flashing red LED alarm.
- One (1) year warranty.
- Certified by CSA for the US & Canada, CE marked for export to EU countries.
- Built-in Reverse Osmosis pretreatment lowers operating cost by economically removing 95-98% of the contaminants from the tap water.
- You can install the spare DI tank yourself, whenever you need it - even on weekends!
- If the DI tank exhausts in the middle of an experiment, or during a weekend, you can install the spare tank.
