Type 1 Ultrapure Biological Low TOC Water Purification System

WG Series: WG301UVUFB / 311UVUFB / 301 UVUFR / 311UVUFR


Made in USA Low-cost of Ownership Compact design Quick change, cartridge – no tools needed

2.5 LPM* of 18 MΩ Type 1 reagent water on demand

Intuitive, user-friendly touch screen interface

Real time quality monitoring with leak detection

Premium quality ion exchange resin

Large capacity, low cost consumable cartridges

Replacement cartridges are fresh and made in the USA. 1 year shelf life.


Water is purified using a staged purification process which includes high-purity ion exchange resins to remove dissolved minerals, ultraviolet light for bacteria sterilization and TOC reduction, and ultrafiltration for pyrogen removal and nuclease free water. As water exits the system, a final filter removes particulates and bacteria to reach Type I water specifications.

Lab Water Purifiers

Solutions are sensitive to contaminants, so any imbalance in the mixture invalidates the results of your experiment. Impure water contains contaminants that pose risks. As a result, water should undergo a purification process to reach a certain level of purity. Our lab water purifiers here at Yamato can help you produce ASTM Type 1, Type 2, and Type 3 water quality. Besides that, our lab water purifiers can help you with the following applications:

Buffers and reagents

A buffer corrects the pH level of any solution. On the other hand, a reagent stimulates a reaction to detect the absence or presence of other substances. Both solutions are prepared by dissolving solid reagents in pure water that are free from any substances that affect the acidity or pH level of the solutions.

Since water is a major solvent involved in creating these solutions, a deionized water system for laboratories is necessary to produce water with high levels of purity. The Yamato Auto Pure WA300 series water purifiers can remove dissolved minerals through high-purity ion exchange resins to process high-quality pure water, which is ideal for preparing both solutions.

Cell culture

Normal water contains compounds that affect cell culture which includes bacteria, endotoxin, organic ions, and organic compounds. These contaminants can cause chemical reactions, changes in pH levels, and disrupt or kill various cells.

Moreover, water is also used in producing buffers and rinsing bioreactors and other materials. Therefore, producing laboratory grade water is necessary. This is usually achieved using Yamato Auto Pure WB300 series water purifiers. These units are great in removing bacteria and particulates to reach type 1 water quality, the highest level of purity in water.

Reverse osmosis

In order to make Type 1 or Type 2 water, feed water quality is important. Reverse osmosis is used as pretreatment of raw water just before feeding it to water purifiers which can produce Type1 or Type 2 water.


Traditional method of producing purified water is distillation, which is the process of separating liquid mixtures through condensation. Academia and certain applications require the heat treated distilled water. Yamato Auto Still series water purifiers can produce distilled water.
