The ECO 16 can be used to process 14 Ø 16 mm test tubes plus 2 Ø 22 mm test tubes simultaneously. Electronic temperature control ensures temperature regulation from ambient to 160 °C and the analysis time can be set from 1 to 199 minutes or continuous. An LED display shows  the temperature and time remaining.  An acoustic signal indicates the end of analysis and the instrument switches off automatically. For increased safety and reliability a safety shield is available.
