AFTER USE
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 in the section Safety and
Installation. We recommend that the blocks should be allowed to cool to 70°C or below before being
removed from the heating unit.
To remove an insert block, screw the extractor tool into the threaded hole and lift the block out
vertically. Never leave the extractor tool in the block while it is being used in the Dri-Block ® heater.

USER MAINTENANCE
Before cleaning your unit, disconnect it from the power supply. The outer case of the Dri-Block ®
heater may be cleaned with a cloth dipped in water or ethanol (methanol can also be used). No part
of the case or cover should be immersed in the solvents. Do not use aggressive solvents such as
acetone or abrasive cleaners. Do not use bleach or strong acids.
Before using any cleaning or decontamination method except those recommended here, the
responsible person should check with Techne that the proposed method will not damage the
equipment.
