Water Purification Systems

Most lab water purification systems spend half their shelf-life in a shipping container coming to the United States from overseas. By the time they arrive in your lab, they’re closer to expired than new.

You wouldn’t buy an expired Brita filter for your water at home. What about your lab?

Every type 1 ultrapure water purification system filter from Yamato is made in the USA and guaranteed to give you a full year of shelf life.

Water purification systems that scale with your lab

Make reagent grade and molecular grade purified water in the volume you need when you need it. Plan your filter cartridge replacement purchases quarterly because you know your next round of replacement cartridges won’t be expired when you bring them out of your supply room. 

Yamato Auto Pure Water Purification Systems 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
  • Large capacity cartridges for your convenience

Since Auto Pure water purification systems are made in the USA, yours doesn’t waste half its useful life in an overseas warehouse, then a shipping container. Your lab pays for a full year of shelf-life and you get it. That way, you can schedule your cartridge replacement purchases easily without worrying you’ll waste budget on expired filters or run out of filters unexpectedly

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. 

You can also choose a purification method, depending on your application requirement and water quality.

Because of the order of the treatment process, Auto Still Water Purification Systems can produce two different qualities of distilled 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 predictable cost

Avoid hidden expenses in your laboratory by choosing the right lab water purification system. Save on costs without compromising quality. 

Our 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.

Save storage space and the burden of reorders.

You use a ton of Ultrapure water for buffers, reagents, and more. If you buy in bottles, 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

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.
