Recommended laboratory water purification and reverse osmosis system

Ultra Clear ™ TWF EDI systems contain all the necessary blocks to get clean and ultrapure water from tap water. plant running efficiency is > 30% when working with fresh water. The reverse osmosis system is followed by an in-line electrodeionization system, after the passage of which the water has conductivity values ranging from 0.06 to 0.2 μS/cm. Water that has passed through the electrodeionization stage can be drained from the built-in storage tank. Each system is equipped with modern and economical cleaning technology. The resulting water has the following quality indicators: electrical resistance equal to 18.2 MΩ*cm; the content of total organic carbon in the range from 10 to 1-3 ppb. Water with these indicators exceeds all quality standards for laboratory water, including: ASTM Type 1, CLSI and ISO 3696 Type 1. All systems, including the UF ultrafiltration system, produce the highest quality water. This system allows to obtain ultrapure water with no RNase, DNase and DNA.
