The CHA-700 autosampler is extremely compact. Unique in its kind, it was designed to be installed beneath the AT-700 titration unit, saving valuable space on the lab bench or under a hood. Simple and cost-effective, the CHA-700 offers important features such as the ability to continuously load samples into any position on the sample holder, without interrupting the analysis sequence (e.g., samples arriving at different times or urgent analyses). The analytical sequence can also include the execution of different programs on the samples being analyzed, at the operator’s discretion.
Identification data for preloaded or “on-the-fly” loaded samples, as well as variable data such as weight, volume, etc., can be entered at any time, even during the analysis, without interrupting the analytical cycle.
The supplied stirrer is a mechanical stirring rod. Washing between samples takes place in a dedicated washing vessel (immersion).

The CHA-600 autosampler is highly efficient and features a shower washing system to ensure cleanliness when analyzing samples that leave difficult-to-remove residues on the sensors (e.g., precipitation titrations) or when cross-contamination needs to be eliminated. The shower washing is performed by a pump, and water or suitable solvents can be used for cleaning. Washing takes place in a container located outside the sample holder, which is automatically emptied after each wash using a second pump (drain). The water or washing solvent is aspirated and discharged into special containers via tubes.
The CHA-600 offers the ability to continuously load samples into any position on the sample holder, without having to interrupt the sequence being analyzed (a very useful option when the samples to be analyzed do not all arrive at the same time but at different times, or for the analysis of “urgent” samples).
The analytical sequence can include the execution of different programs on the samples being tested, at the operator’s discretion.
The identification data for preloaded or “on-the-fly” loaded samples, as well as variable data such as weight, volume, etc., can be entered at any time, even during the analysis, without interrupting the analytical cycle.
The supplied stirrer is magnetic. A mechanical stirring rod is optional.
It is supplied complete with all accessories for proper operation (excluding vessels) and for connection to the AT-710 M or S titrant unit.
