1.4 Open and Close Lid
The lid of the Thermal Cycler can be adjusted to come into contact with and
apply pressure to the tops of the reaction vessels. Heating of the lid protects
samples from condensation.
To open the lid:
1. Turn the lid knob counterclockwise (see the ‘Loosen’ arrow symbol on the top
surface of the lid knob) to raise the pressure plate.
2. Grasp the lid handle so that the handle clamp is pulled toward the lid handle.
3. Lift up the lid handle until the lid opens vertically. You can then place
reaction vessels in the sample block or remove samples from the block.
To close the lid:
1. Place reaction vessels into the wells of the sample block.
2. Hold the lid handle and handle clamp, and then let the lid touch the chassis
until you hear ‘click …’ sound. The lid will be locked in place.
3. Turn the lid knob clockwise (see the ‘Tighten’ arrow symbol on the top
surface of the lid knob) to reduce the lid height until resistance is felt. Then
continue to turn the lid knob clockwise until you hear ‘click …’ sound. The
lid is now pressing on the reaction vessels.
