Pure Line Water Purification System

Pure water at a low cost.

Your lab should have a steady supply of pure water, but it shouldn’t cost you a fortune. With Yamato’s Pure Line Water Purification Systems, you can continuously produce deionized water at a low cost. Wanna learn more? Read our free water purification systems buyer’s guide!

The WE200 is a benchtop water purification system with an integrated Reverse Osmosis (RO) membrane cartridge, which prolongs your consumables’ life. That means you can expect that your unit will perform excellently in the lab as it should. Not only that, but WE200 is made in the USA and also comes with membrane filters. These add another layer of protection for your pure water against contamination. Get a consistent supply of pure water—without compromising your lab budget.

Lab Water Purification Systems

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 purification systems here at Yamato can help you produce ASTM Type 1, Type 2, and Type 3 water quality. Besides that, our lab water purification systems 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 purification systems 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 purification systems. 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.
