Evoqua LaboStar® Pro TWF

From Tap to Ultrapure Water in Only One Innovative Step

The LaboStar® PRO​ TWF systems produce ultrapure water straight from your drinking water supply. This equipment incorporates a pre-filtration unit and a reverse osmosis membrane. The pure water collects in an integrated tank and is finally circulated through the polishing module by a circulation pump. The user can extract either Type III water from the built-in 7l storage tank or Type I water from the dispenser with a quality of 0.055 µS/cm, equivalent to 18.2 MΩ-cm, and TOC of between 1 and 10 ppb, depending on the system type. The RO water quality is displayed as well.

The LaboStar PRO TWF equipment can cost-effectively produce small amounts of analytical-grade water. The water quality exceeds all relevant standards including ASTM Type I, CLSI and ISO 3696 Type I. System can be upgraded with 30 or 60l storage tank.

A conductivity sensor constantly measures the product water purity in the recirculation loop. A positively charged 0.2 µm sterile filter at the dispenser removes bacteria and endotoxins, eliminating the need for an expensive ultra-filter. An uncharged 0.2 µm sterile filter is also available. LaboStar™ PRO TWF systems are delivered with the first set of modules and filters.
