PURELAB® Classic

Features

The PURELAB Classic features continuous water quality monitoring to deliver ultrapure water with a low bacterial specification. The system combines high performance with economy to deliver 18.2 MΩ.cm Type I ultrapure water at a very cost-effective price. This compact system is ideal for a wide range of applications including critical reagent preparation, critical glassware washing, molecular biology, bacterial and mammalian cell culture, electrophoresis, HPLC, ICP-MS, Ion chromatography and TOC measurement.
