When you require the ultimate in water purity, PURELAB Chorus 1 provides the perfect solution. Consistently delivering water purity of 18.2 MΩ.cm (Type I+/I) and underpinned by the advanced PureSure deionization system, the PURELAB Chorus 1 enables you to focus on attaining accurate results while ensuring an uninterrupted workflow.
Advanced PureSure Deionization – Eliminates trace ions that leach into your water and provides advanced warning to change the purification packs.
Fully Recirculating – Ensuring microbial purity and guaranteeing pure water at the point-of-use.
Real-time TOC Monitoring – Provides complete confidence in organic purity.
Integrated Filtration – Ultrafiltration or microfiltration filters out endotoxins, proteins, nucleases, and particulates.
