The Yamato Laboratory Water Purification System: Purity in every drop

With our ultra-intelligent water purification systems, the purest clinical lab water is just within arm’s reach. Each Yamato water purification system can help you eliminate the most notorious water contaminants, giving you the highest quality water for your assays and experiments. Get reagent grade and molecular grade purified water. With Yamato lab water purification systems, you can ensure purity in every drop.

Nothing but high purity water.

In a word, Yamato Auto Pure Water Purification Systems are state-of-the-art. They have undergone the most rigid performance tests, ensuring you will get nothing but pure water after an intricate four-stage filtration process. This line’s purifiers can swiftly remove ionic and organic contaminants down to trace levels through high-purity ion exchange resins. These laboratory water purification systems also have real-time monitoring, intuitive touch-screen panels, and large capacity cartridges for your convenience, so you can rest assured that the filtration and quality will meet your needs.

Multipurpose & conventional.

We know you have different budgets, assay requirements, and lab sizes. That is why you have the freedom to choose from our Auto Still Water Purification Systems, which have two different water purifying methods: conventional distillation and deionization by ion exchange resins. You can also choose a purification method, depending on your application requirement and water quality.

Because of the order of the treatment process, our Auto Still Water Purification Systems can produce two different qualities of distilled water. WG251/1001 and WG204 distillate water after the ion exchange resin, so they produce Type II distilled water. Meanwhile, the WA511/711/731and WS201/221 distillate raw water, so they produce Type IV distilled water. All these models (except WS201/221) can produce Type I deionized water.

Pure water at a low cost.

Avoid hidden expenses in your laboratory by choosing the right lab water purification system for your site.

Save on costs without compromising quality. Yamato’s Pure Line Water Purification Systems are affordable with intelligent features and design. Now, you don’t have to sacrifice lab space and spend a fortune to get pure water for your assays. Use our two benchtop series, WE200 and WL200/220/220T. If you need a compact, standalone unit that can handle large volumes of deionized water, get our power-saving, economic WL100 model.

Compact and mobile.

You deserve equipment that fits your workflow and complements your lab setup. Yamato’s Labo-Cube Water Purification System is space-saving and versatile. The sleek Labo-cube purifier will fit snugly under your lab’s fume hood, a sink, or a table. You can produce Type II deionized water anywhere and anytime you want.

Save storage space and the burden of reorders.

To ensure test results are reliable, labs go through a ton of high-quality Ultrapure water for buffers, reagents and more. The water is stored, rationed, and carefully used. And when it runs out, operations in your lab come to a halt.

In a time of stock and shipping unpredictability, more labs than ever purify their own personal stock of Ultrapure water with a laboratory water purification system instead of ordering it. That also means they:

  • React quicker to the changing needs of their labs.
  • Save storage space taken up by excess amounts of bottled Ultrapure water.
  • Reduce time spent on administrative tasks such as ordering water and keeping inventory.

Make Ultrapure Water In-House by investing in the right water purification system.

Find the right system for your needs.

Water is essential in your lab, and you use a lot of it. Sure, you can buy lab quality water in jugs. But it’s far more economical and efficient in the long-run to buy a pro water purification system and water filters, designed to provide you with the pure water you need to complete your work.

Improve control in critical diagnostic procedures with a water source in-house, by using reagent grade pure water, instead of deionized or distilled water. Or opt for a laboratory water purification system that makes molecular grade water, which is a more economical choice for your lab in the long-run, and allows you to always have the assurance that the high quality of water you need is free from DNase, RNase and protease contamination.

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 I water, Type II water, and Type III 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.
