Graphite Digestion System XOSM-24N, 24 Positions (CAT#: STEM-AL2-4455-ZJF)

The system is a multi-position graphite digestion block for sample pretreatment and acid-removal procedures. Samples are heated in individual wells within a high-purity graphite heating structure. A corrosion-resistant coating separates exposed surfaces from aggressive laboratory reagents. Programmable PID control supports staged temperature ramps and controlled holding periods. The surrounding heating arrangement is designed to reduce temperature differences between sample positions. Multiple vessels can be processed under comparable conditions during the same batch. Alarm and automatic-stop functions support temperature-controlled operation. The unit is suited to preparation workflows preceding atomic spectroscopy and related elemental analysis.
