vario MAX



High end for your macro samples

Due to its unique crucible technology the vario MAX offers unique opportunities. The samples are easily weighed into reusable crucibles and analyzed fully automatically. Liquid or solid does not make a difference here, the vario MAX analyzes it in one run.

Especially for inhomogeneous samples or soil samples the large sample size in the gram range is crucial. The automatic ash removal enables the operation of large series of mineralic samples without any problems. Its intelligent design with enclosed gas flow enables an unrivalled precision of the analysis.
This makes the vario MAX a class of its own.

Three dedicated versions, optimized for different application ranges are available.

Modes



vario MAX CN
The vario MAX N/CN may be operated in carbon/nitrogen mode or the faster N/Protein mode according to the Dumas combustion method. This analyzer is particularly suitable for meats, grains, feeds, dairy products and beer for the determination of protein (N). In CN mode typical applications include plants tissue, soils, manure and compost samples as well as liquid extracts of these materials. The vario MAX is a fast, safe and environmentally friendly alternative to the classical Kjeldahl method. The large reusable sample crucibles result in easy sample preparation for solids, liquids or semi-solids.

vario MAX CNS
Macro analyzer for the determination of carbon, nitrogen and sulfur.
In either CN or CNS mode typical applications include plants tissue, soils, manure, compost samples as well as industrial products.

vario MAX CHN
The vario MAX CHN analyzer is uniquely designed to address the needs of carbon, hydrogen and nitrogen analysis in fossil fuels and incineration feed stocks. In addition to gross caloric value calculations of these fuels, the vario MAX CHN has also found new applications in the analysis of plant growth material and environmental samples. The MAX is the only CHN macro analyzer which utilizes re-usable open crucibles with an automatic sample feeding system.

Specifications



Measuring method
