Reverse osmosis water treatment system for ultrapure water

The LaboStar PRO TWF system allows you to get ultrapure water using a drinking water supply system as a source of feed water. This equipment includes a pre-filtration module and a reverse osmosis membrane. Purified water accumulates in the built-in tank and then is fed to the polishing module with a circulating pump. As a result of the operation of the system, the user can get purified water of both type III and type I. The intake of purified water of type III comes from a built-in 7-liter tank. The intake of purified water of type I is carried out using a dispenser, such water will have the following characteristics: conductivity 0.055 μS/cm, which is equivalent to a resistance of 18.2 MΩ*cm; The level of total organic carbon (TOC) ranges from 1 to 10 ppb, depending on the type of system. The quality of the water passed the reverse osmosis module is displayed on the display. With the help of Labostar PRO TWF equipment, small amounts of analytical grade water can be obtained at no extra cost. The quality of produced water exceeds the requirements of all standards for laboratory water, including: STM Type 1, CLSI and ISO 3696 Type 1. The system can be upgraded to work with tanks of 30 and 60 liters.
