The Metrohm 730 Sample Changer: powerful and versatile automation for serial analyses
The Metrohm 730 Sample Changer is an automated solution designed to improve productivity and standardisation in laboratories performing repetitive series of measurements or titrations. Thanks to its modular design and versatile communication interfaces, it integrates seamlessly into the most complex automation chains and meets the growing demands of modern laboratories in both industrial and analytical environments.
This system is capable of automatically processing large series of samples for titration, dosing, pH, conductivity or ion measurement. It can be configured with different types of heads (titration, transfer) and up to two towers, each of which can accommodate peristaltic pumps and magnetic stirrers. Interchangeable racks, capable of holding different beaker formats, allow the layout to be customised to meet the specific requirements of each protocol.
The device allows fine programming of analysis methods, including the definition of start and end sequences, electrode conditioning, automated rinsing and the use of special beakers. Method learning via LEARN mode and the ability to store customised sequences ensure great flexibility of use, even for the most complex protocols. These features are particularly useful in environments requiring high reproducibility and traceability in accordance with GLP standards.
Thanks to its numerous interfaces (RS232, Remote, External Bus), the 730 Sample Changer can control or be controlled by compatible third-party instruments, including titrators, pH meters, conductivity meters and Dosimat/Dosino dosing units. It can also operate in a network with several peripherals, facilitating integration into larger laboratory control systems such as TiNet.
In addition, the Swing Head option (759) significantly increases the number of samples that can be processed. This head, capable of precise movements between beaker lines in multi-row racks, is available with a titration head or transfer head for automatic pipetting to a central titration cell.
Robust, reliable and designed for intensive use, the 730 Sample Changer is an essential tool for laboratories looking to automate their analytical sequences in a scalable way. Its flexible architecture, ability to handle complex methods and seamless integration with Metrohm solutions make it the platform of choice for saving time while ensuring accurate and reproducible results.
