Benefits of an automated sample changer system for labs dealing with a large number of samples or under particular time and cost pressures
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 clear structured keyboard, programming of the 730 sample changer is simple.
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 preprogrammed.
Thanks to optimum rinsing between the individual analyses, the reproducibility of the results is outstanding.
The rugged and compact construction of the 730 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 complex titrations, the sample changer controls several titrators and/or pH or conductivity meters, Dosimats, etc, and is itself controllable via different interfaces.
Where can sample changers be used to effect? With a large number of samples.
Where a high level of automation is required.
Where the sample preparation must be rationalised.
Where there is no time for sample preparation.
Where samples must be dissolved immediately before the titration.
Where highest reproducibility is demanded - even for small numbers of samples.
Benefits include: Higher sample throughput.
Operation requires no special knowledge.
Operating personnel are freed for the duration of the analysis.
Contact with toxic chemicals is reduced to a minimum.
System operates without supervision, even overnight and during breaks.
Connection to existing Metrohm titrators is assured.
The company's product range includes models with one or two liftstations, with magnetic or propeller stirrer.
After the titration, the sample is siphoned off by the integrated pump and disposed of.
The flexible communication possibilities also allow connection to third-party devices. Request a free brochure from Metrohm UK ...
