Yamato Auto Still WG205 Small Capacity Water Purification System
Yamato’s Auto Still WG205 is an economical multi-purpose benchtop high purity water purification system with 20L tank capacity. It is equipped with a pre-treatment cartridge to increase the life span of all consumables. In addition, it displays alerts for consumable replacements and keeps track of replacement history. The WG205 produces ASTM type 1 deionized water and type 2 distilled water kept in a 20L storage tank.
- Pre-treatment cartridge removes bacteria, trihalomethane, residual chlorine, organic and dust
- High performance ion-exchange resin cartridge (CPC-S, 4L) brings high purity water with low electric conductivity and TOC
- Optional membrane filter at water sampling port
- Displays replacement of consumables
- Equipped with automatic bolier drainage function
- Compact. Can be installed in areas with limited space.

*3 Dimensions excludes protrusions.
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.
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.
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.
