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. A 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.
