719 S Titrino Potentiometric Titrator

719 S Titrino from Metrohm: precision for automated titration

The Metrohm 719 S Titrino is a titration device designed to perform fast and accurate titrations to the end point. This system is particularly suitable for quality control, environmental analysis, pharmaceutical and food analysis laboratories that require efficiency, reproducibility and traceability in their analytical processes.

Thanks to its intelligent and intuitive design, the 719 S Titrino allows analyses to be started immediately using ready-to-use methods, while giving the user the freedom to create, modify or save their own methods. This gives the device great flexibility for both standard analyses and customised applications.

At the heart of the system is a user-friendly interface with a multifunction keypad with dedicated keys for parameters, configuration, sample data and user method management. The integrated LCD screen clearly displays titration parameters, dosed volumes, titration curves and calculated results.

The 719 S Titrino can be connected to a computer, printer, magnetic stirrer, balance or sample changer via its numerous interfaces, including an RS232, an analogue port and specific connections for electrodes, temperature sensors and peripherals. This makes it possible to control the device remotely using Metrodata VESUV or TiNet software, enabling automated data acquisition and evaluation.

Features such as pH calibration, data storage, statistical management (average, standard deviation), drift correction and automatic conditioning of the titration vessel make it a powerful tool for routine titrations or complex analyses. Users can define customised calculation formulas, enter method-specific constants and choose from a wide range of result units.

Its dosing system is optimised by adjustable parameters such as minimum and maximum dosing speed, pause times, titration dynamics and stop criteria based on drift or time. All this is compatible with different burette volumes and electrode types, further increasing the instrument's versatility.

The 719 S Titrino complies with validation and GLP (Good Laboratory Practice) requirements and provides comprehensive printed reports with method ID, results, pH, dosed volumes and statistics, ensuring data quality and reproducibility.

The 719 S Titrino is a complete, robust, scalable and productivity-oriented analytical system, suitable for the high demands of modern laboratories.
