Key Benefits

This Ultrapure Water System directly addresses the core needs of analytical and life science laboratories: water quality consistency, operational efficiency, and regulatory confidence.

• • Uncompromising Water Purity for Sensitive Analyses – The 18.2 MΩ·cm resistivity and 1–3 ppb TOC levels ensure that your water meets Type I+ standards for HPLC, LC-MS, and mammalian cell culture. You can trust that every experiment starts with the purest possible reagent.

  • PureSure Technology Prevents Contamination – The advanced PureSure deionization system prevents the release of weakly bound ions back into the water, maintaining resistivity and protecting your samples from unexpected impurities.

  • Real-Time Monitoring for Complete Confidence – Integrated TOC tracking and resistivity monitoring provide continuous verification of water quality. Data can be exported via USB for audit trails and compliance documentation.

  • Mercury-Free UV with Extended Lifespan – The innovative Xe mercury-free UV technology delivers effective microbial control with a 5-year lamp lifespan, reducing environmental impact and maintenance demands.

  • Flexible Dispense Solutions – The Halo Advanced Dispense unit offers variable flow rate, drop-by-drop control, locked dispense, and auto-volume dispensing, all with purity monitoring at the point of use.

Address Customer Pain Points

Struggling with inconsistent water quality that compromises your HPLC or cell culture results? Variable resistivity, elevated TOC, and bacterial contamination are common frustrations in busy laboratories. The PURELAB® Chorus 1 eliminates these headaches:

• Inconsistent water purity – The PureSure deionization system with real-time monitoring ensures that resistivity remains at 18.2 MΩ·cm and TOC stays below 3 ppb. No more worrying about unexpected impurities ruining your separations or cell lines.

• Time-consuming manual quality checks – The integrated TOC monitor and resistivity display provide continuous, real-time water quality verification. Exportable data via USB eliminates manual logbooks and simplifies compliance.

• Equipment downtime and unplanned maintenance – The early warning system alerts you when purification packs need changing, preventing unexpected interruptions to your workflow.

• Microbial contamination risks – Continuous recirculation, full-spectrum UV treatment at the point of use, and integrated ultrafiltration work together to maintain bacteria levels below 0.001 CFU/ml and eliminate endotoxins and nucleases.

• Environmental and cost concerns – The mercury-free UV lamp with 5-year lifespan reduces hazardous waste and lowers replacement costs.

By removing these pain points, the ELGA PURELAB® Chorus 1 Ultrapure Water System lets your team focus on groundbreaking research rather than water quality troubleshooting.
