After Use
1. When you have finished heating samples, remember that parts of
the unit – the tubes, blocks and associated accessories – may be
very hot. Take the precautions listed earlier. We recommend that
the blocks should be allowed to cool to 70°C before being removed
from the Dri-Block
® . They will still have to be handled with care
2. If you need to remove an insert block while it is hot, screw the
extractor tool into the thermometer hole and lift the block out
vertically. Never leave the extractor tool in the block while it is being
used in the Dri-Block
® .
