The PURELAB Chorus 1 from ELGA LabWater represents the pinnacle of ultrapure water purification technology, engineered for laboratories that demand absolute accuracy, reliability, and consistency. Delivering Type I+/I ultrapure water directly from tap feed, this intelligent system ensures the highest water purity for life science, analytical, and general research applications — including HPLC, GC-MS, ICP-MS, molecular biology, cell culture, and clinical diagnostics.
With advanced PureSure® deionization technology, the PURELAB Chorus 1 guarantees 18.2 MΩ·cm resistivity and < 5 ppb TOC, exceeding ASTM Type I, ISO 3696 Grade 1, and CLSI CLRW standards. The innovative PureSure system extends consumable life, maximizes uptime, and minimizes running costs — giving laboratories uninterrupted access to reliable, ultrapure water.
This fully recirculating system ensures microbial purity and guarantees high-quality water right at the point of use, eliminating contamination risks and maintaining purity 24/7. Integrated real-time TOC monitoring continuously verifies organic purity, while intelligent sensors track resistivity and flow for total confidence in performance.
The PURELAB Chorus 1 also features integrated ultrafiltration or microfiltration to effectively remove endotoxins, proteins, nucleases, and particulates — delivering consistent purity with fewer maintenance intervals. With data capture via USB, laboratories can validate performance, record quality metrics, and install software updates for complete operational accountability.
Compact, modular, and beautifully designed, the PURELAB Chorus 1 fits seamlessly into any laboratory — under-bench, wall-mounted, or stacked for scalability. Its intuitive touchscreen interface simplifies operation, while the energy-efficient design reduces environmental impact and total cost of ownership.
For laboratories across Trinidad & Tobago and the Caribbean, the ELGA PURELAB Chorus 1 delivers the highest water quality for the most demanding analytical and life science applications. It’s the perfect solution for researchers who require absolute purity, traceability, and reliability — supported locally by Southern Medical Supplies Limited (SMSL), your authorized ELGA LabWater distributor for ultrapure water systems and clinical analyzer feed solutions.
