Yamato Labo Cube WL Series Lab Water Purifier



Yamato’s Labo Cube WL320 water purifier is space saving and can be installed under a fume hood or sink, or on a table. It comes with rubber legs (WL320A) or movable casters (WL320B). Standard equipped with membrane filter at the sampling port of the one touch coupler connecting resin hose. A water leakage detector forcefully shuts off the feed water solenoid valve when water leakage is detected. It displays alerts for consumable replacements and keeps track of replacement history. The Labo Cube® WL series continuously produces ASTM type 2 deionized water.


  • Deionized water compliant with ASTM D1193 Type2 / JIS K 0557 A4 level, suitable for high sensitivity trace analysis
  • Easy operating digital display
  • Standard equipped with membrane filter at water feeding port
  • Equipped with water leak detection function that stops water supply in case water leak occurs, by activating the electric leakage breaker
  • Displays replacement of consumables

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.
