Labonova® Direct

Integrated Pure and Ultrapure Water System

Labonova® Direct is designed to cost-effectively produce analytical grade ultrapure (Type I) water and pure (Type III) water in one integrated system from tap water. The Ultra pure water quality exceeds all relevant standards including ASTM Type I, CAP, CLSI and ISO 3696 Type I. This extremely compact purification system can produce up to 1.5 l/min type I ultrapure water and 10 l/h type III pure water, that can meet most needs of today’s laboratories. Labonova® Direct is an economical and effective choice for the laboratory needs of pure and ultrapure water compared with other systems. 

Labonova® Direct is delivered with the first set of modules and filters, that is ready for use. This equipment incorporates a pre-filtration unit and a reverse osmosis (RO) memebrane in one single compact module. The Type III quality reading of the reverse osmosis water appears in the display. The pure (Type III) water is stored in an integrated 7 l reservoir. When 18.2 MΩ.cm Type I water is required at the point of use, RO water is sent from the reservoir through high capacity polishing cartridges for further purification. With the addition of a dual wave-length UV lamp, and enhanced organic removal DI polishing cartridges, TOC levels of <5ppb can be obtained. It is the ideal choice for HPLC, GC, IC, TOC analysis, etc.

Labonova® Direct features three stages of purification-pretreatment, polishing and a positively charged 0.2μm sterile filter at the point of dispense to remove bacteria and endotoxins. The system also includes a vent filter to maintain water quality in the storage tank.
