Adaptation of programs from other thermal cyclers
Since the QIAamplifier 96 thermal cycler is a very fast device, it may be necessary to reduce the
heating and cooling ramp when running protocols from other (slower) thermal cyclers (see section
Adjusting the ramp rate). Alternatively, the hold times may be extended.
13.6
Loosening the lid wheel in case of blockage
When the heated lid is in the highest or lowest position, it may happen that the lid wheel is
uncoupled. In this situation the clutch mechanism is active in both directions (there is a clicking noise
in both directions).
To unlock the lid wheel, press down the metal pin on the top of the lid wheel with a pen. This
overrides the clutch mechanism. Take care not to apply excessive pressure.
Lid blocked in the top position:
1.
Press down the metal pin.
2.
Lid blocked in the bottom position:
1.
Press down the metal pin.
2.
Carefully turn the lid wheel counterclockwise until it moves again without resistance (no more clicking). Release the pin
and turn the lid wheel upward until the pressure is completely released. Open the lid.
Important
: When the clutch mechanism is active, (= optimal contact pressure reached) do not, under
any circumstances, press the metal pin again to increase the contact pressure further. This will
damage the samples and the device.
