- All additions (sodium hydroxide, water, boric acid) and cleaning steps (distillation and titration residues removal, titration vessel cleaning) are automatic, depending on the model.
- Use the Vreceiver™ with boric acid and indicators for standardized receiving solution preparation.
- Maintain operating parameters such as steam flow regulation (10–100%) and delay time settings (0 sec to 99 min 59 sec) as needed.
- Ensure the distillate temperature remains below 35 °C using the titanium condenser for accurate recovery.
These features support high recovery performance without manual intervention.
