When cycling is complete, proceed to unload the thermal cycler.
Unload the thermal cycler
You can remove the chips from the thermal cycler immediately after the final
extension step at 60°C is complete and the temperature of the block is
£
25°C.
Alternatively, the chips can remain on the block for up to 24 hours at 10°C.
IMPORTANT!
We recommend that you read chips within 1 hour after you remove
them from the sample block.
CAUTION!
PHYSICAL INJURY HAZARD
. During operation, the sample block may
reach temperatures of 100°C. Before removing chips, wait until the block reaches
room temperature.
1.
If you programmed the thermal cycler to perform a 10°C hold after cycling, do
the following to prevent condensation:
a.
Confirm the final extension step at 60°C is complete, then stop the run.

b.
Allow the thermal cycler to sit for at least 10 minutes with the heated
covered closed.
2.
Open the heated cover to expose the chips.
3.
Remove the thermal pads from the sample block and set them on a clean, dry
surface.
Note:
Do not discard the pads. They can be reused multiple times.
