Finishing digestion and removal of samples

  Danger of burns! The inner zone of the 

heating block and the sample vessels get 

hot! 

Never touch the hot glasses or the area 

of the heating block around the mounting 

holes with the bare hands. Always remove 

the samples from the heating block using 

the sample rack and allow them to cool as 

described here.

  Caution: there are  acid condensates in the 

exhaust collector. They can burn you and 

stain the metal parts of your device.  

Wash your hands with water after contact  

with the condensate. Insert the drip tray 

after inserting the exhaust collector in the 

mounting rack.  

Grasp the sample rack using the two red handles.

Lift the rack carefully, together with the exhaust col-

lector, and hang it on the lower hooks of the mounting 

rack.

Leave the exhaust collector on the sample rack until 

the samples have cooled down.

Once the samples have cooled, switch the exhauster 

system off.

Remove the exhaust collector from the sample rack 

and suspend it in the upper hooks of the mounting 

rack.

Insert the drip tray into the mounting rack, into the 

slots below the exhaust collector.

The sample rack can now be removed for further 

processing of the samples.
