Product Summary

ELTRA's CS-580A (with autoloader) is the ideal analyzer for the simultaneous determination of carbon and sulfur in organic samples.

The CS-580A is equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention. The sample loader is available in two versions to accommodate 36 or 130 crucibles. The CS-580A is based on the technology of the CS-580 analyzer and features a vertical resistance furnace with ceramic tube.

The temperature can be set in steps of 1 °C to a maximum of 1,550 °C. Thanks to sample weights of up to 500 mg and more even non-homogeneous materials can be reliably analyzed.
