Removing the samples from the heating block
When the digestion is completed, you should take the
samples out of the heating block but leave the exhaust
collector on the sample rack until the samples have
cooled down. So now you need to lift the sample rack
along with the exhaust collector out of the heating block
and park them.
Grasp the sample rack using the two red handles.
Lift the rack carefully, together with the exhaust col-
lector. Run it along the mounting rail while doing so.
Lift the rack upward until you hear it engage.
Lower the rack carefully onto the hooks, in order to
check that it has engaged correctly. If this is not the
case, lower it again and repeat the above procedure.
Parking the exhaust collector
Grasp the exhaust collector using the two red
handles.
Remove the exhaust collector from the sample rack
and suspend it in the cut-outs at the top end of the
mounting rail.
Front lid on the sample rack
Danger of burn! The front lid gets hot! o
not try to remove the front lid while a dige‑
stion is in progress.
The lid on the front side of the sample rack may be taken
off. Thus you have the samples in view while digestion is
in progress.
For routine digestions you should leave the front lid on.
With the front lid on, less heat will escape so you will
save energy.
Removing and remounting the front lid
Put the sample rack on an even surface.
For taking the lid off, hold the sample rack down and
pull the lid upwards until it can be taken off.
For putting the lid on, insert it in a way as for the
hooks and the fold to engage behind the lower and
middle part of the sample rack frame, as indicated.
