Lab Water Purification Systems

Most labs overspend on ultrapure water by 50% or more. Don’t be most labs.

Yamato lab water purification systems are the lowest cost of ownership and the lowest cost per liter of ultrapure water available to your lab.

Stop wasting budget on brand loyalty

Ultrapure water is ultrapure water. The big 5 manufacturers of lab water purification systems:

  • Don’t give you better quality 18.2 MΩ.cm water.
  • Don’t integrate with your processes better.
  • Dont’ give you better support.
  • Don’t provide unique customization options.

But they DO mark up the purchase price of their lab water purification systems and filter cartridges quite well.

Your Yamato lab water purification system does everything the systems you’re familiar with do. But at a fraction of the cost of ownership and cost per liter of type 1 water.

Change filters less often. Increase process uptime.

Yamato cartridges filter a greater volume of water at a lower cost than equivalent models from other manufacturers.

They’re twice as large at ⅓ the cost.

This means students or lab techs don’t have to change filters as often, and the HPLC, LCMS, ICP-MS, AAS, or other system drawing type 1 water stays online longer.

Make new labs profitable faster.

The cost of ownership of our new Yamato Auto Pure filters after 4 months looks to be about 55% lower than our previous Barnstead filters. We’ve moved 5 of our large systems over to Yamato as a test, and we’ll be moving the rest over at the start of next quarter.

Gurdeep Singh, Lab Director

We’re expanding the lab and invested in 3 Yamato water purifiers. In our analysis, it was one of the easiest ways to make the new lab more viable and recover our investment in a more timely way.

Chris Forbes, Director

The executive team is keeping a close eye on profits in the lab. This is one of the ways we cut costs and increase those profits, and it had an immediate and measurable effect on the lab’s budget.

Water purification systems that scale with your application

Make reagent grade and molecular grade purified water in the volume you need when you need it.

Feed directly to your LCMS, HPLC, or other instruments, or dispense in smaller quantities for your buffers and reagents.

Yamato Auto Pure Water Purification Systems 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 to eliminate leaks.
  • Intuitive touch-screen panels so there’s no learning curve switching from other brands.
  • Large capacity cartridges to maximize your application or instrument uptime.

For diverse lab water purification applications

The Auto Still Water Purification System comes in two different water purifying methods:

  • Conventional distillation
  • Deionization by ion exchange resins. 

Because of the order of the treatment process, Auto Still Water Purification Systems can produce two different qualities of lab water.

Models WG251/1001 and WG204 distillate water after the ion exchange resin, so they produce Type II distilled water. These models can also produce Type I deionized water.

Ultrapure lab water at a lower cost per liter

Independent testing shows every model of Yamato lab water purification system gives your lab a significantly lower total cost of ownership than the equivalent models from other manufacturers.

Pure Line Water Purification Systems are affordable with intelligent features and design. They help you reduce the cost of every single assay.

Save storage space and the burden of reorders

You use a ton of Ultrapure water for buffers, reagents, and more.

In a time of stock and shipping unpredictability, labs can reduce the burden of reorders by opting for larger capacity filter cartridges. Ours are almost double the capacity of the closest competitor.

Reduce time spent on administrative tasks such as ordering cartridges and keeping inventory

Equip your chem store, lab store, or laboratory stockroom with a lab water purification system that’s easy for any operator to use.

Outfit your instruments with an ultrapure water system that treats tap water just as efficiently as the big 5 brands. But reduces your related expenses by 50% or more.

You still get the high quality water that’s free from DNase, RNase and protease contamination.

But you save your lab thousands or tens of thousands of dollars this year.

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.
