REMOVING THE BLOCK
The thermal cycling block can be removed for detailed cleaning or replacement.
First ensure that the unit is disconnected from the power supply and has been allowed to cool if the
unit was previously in use. The two quick release handles located at the front and back of the block are
used to unlock the block. The padlock symbols indicate the direction in which to slide the handles:
open to unlock and closed to lock. When the block is unlocked it will simply lift out of the unit. Never
lift or carry the block by one quick release handle, always use both handles or support the block from
underneath.
When refitting the block, slide the quick release handles in the opposite direction to lock the block into
the thermal cycler. The software will register and calibrate the unit for the new block.
It may be necessary to edit the heated lid parameters for a new application; for example if the in-situ
PCR block is fitted for use with hybridisation slides then it is necessary to switch the heated lid OFF as
excess heat can cause evaporation of samples.
