Product Description
The vertical double-tube configuration accepts solid or powdered specimens with quartz or alumina supports. Single- or double-pushrod operation is available, and the control computer modifies test parameters through its user interface.
The system controls temperature, records expansion, and provides automatic data output, experiment archiving, and retrieval.
