The digestion process can be interrupted at
any time by pressing the STOP button. In this
case, the heating is switched off. The Scrubber
will continue to operate until the STOP button is
pressed for a second time.
Cooling the digested samples
Both the sample rack and the fitted suction module are moved into the cooling position. The Scrubber
or the water jet pump will continue to operate. After the cooling procedure is finished the Scrubber
can be switched off by pressing the STOP button.
Removing the sample rack
Swivel back the suction module and remove the sample rack with the cooled samples.
After the digestion is finished the instrument should remain connected to the power for another 30
minutes. Thus the instrument is cooled by a built-in ventilator and the service life of the built-in display
is extended.
