When and why you automate titration
The benefits of an automated sample changer system for labs dealing with a large number of titration samples or under particular time and cost pressures are explained
Benefits of an automated sample changer system for labs dealing with a large number of titration samples or under particular time and cost pressures Metrohm has long been able to perform analyses automatically, however large sample throughput can only be achieved using an efficient sample changer system, which suits your throughput, sample size, collection vessel shape, sample preparation and budget

The benefits of automating your titration system, are that it will provide.
High sample throughput.
Reproducible results.
Operator requires no special knowledge.
Operational personnel are freed for the duration of the analysis.
Contact with toxic chemical is reduced to a minimum.
The system can operate 24 hours a day, seven days a week.
Large sample throughputs and high reproducibility can be achieved using the efficient Metrohm sample changers.
But also small series and even single samples profit from the perfectly reproducible results in automated sequences.
The use of a 730 sample changer benefits the user in many ways.
High throughput and automation of sample preparation are major features.
However a sample changer also enhances the reproducibility of small series and even single samples and this greatly improves the reliability of the results.
Thanks to its clearly structured keyboard, the 730 sample changer is easy to operate.
The sequences are programmed via the straightforward dialogue in the language of your choice.
Depending on the complexity of the sequence, up to 30 methods can be stored in the method memory.
To ensure easy operation, the six most frequently used sequences have been pre-programmed.
Thanks to optimum rinsing between the individual analyses, the reproducibility of the results is outstanding.
The rugged and compact construction allows the use of a wide range of sample racks for up to 24 samples and for glass or disposable beakers with volumes between 75 and 250ml.
Pumps or Dosimats deal with the solvent addition.
As the master of a complex titration system, the sample changer controls several titrators and/or pH or conductivity meters, Dosimats, etc, and is itself controllable via different interfaces. Request a free brochure from Metrohm UK ...
