The Heated Lid
The heated lid is an integral part of the Touchgene Gradient. It can be switched “On” or
“Off”, see ‘Program Defaults’ or ‘Editing screen’.
To open the lid lift the back of the handle as shown and use it to lift the lid. To close the lid
lower the lid onto the block with the samples in and press the handle shut.
To adjust the pressure on the
samples: Adjust the red rotating knob
anticlockwise to give minimal pressure, shut
the lid and latch it. Gently rotate the knob
clockwise until you can just feel pressure
beginning to be applied. Rotate the knob a
further quarter of a turn and this will give
the correct pressure. Do not over-tighten
the knob as this will cause deformation of
the silicone rubber membrane and reduce
the effectiveness of the lid. Once the
pressure has been set it does not need to be
adjusted unless a different block, and hence
a different type of sample holder, is used.
