The LaboStar® PRO system is a cost effective means of producing analytical grade water. This extremely compact ultrapure water system can be used on a laboratory bench. The water produced by the system has a conductivity of 0.055 µS/cm (equivalent to 18.2 MΩ-cm) and a TOC value of < 10 ppb. The water produced by the ultraviolet (UV) version has a TOC value of 1 – 5 ppb.
