USER OPERATION AND CONSUMABLES
HEATED LID
To release the heated 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 containing the samples and press the handle down to shut.
The silicone rubber mat supplied with the unit (Part No. 6104978) is for use with microplates when
sealing using a plastic adhesive film. The mat should be placed on top of the sealing film to ensure good
thermal contact with the heated lid.
The heated lid has a rotating knob to adjust the lid pressure on the samples, allowing for a variety of
consumables to be used. To adjust the pressure:
Do not over-tighten the knob as this will cause deformation of the silicone rubber membrane (where
used) and reduce the effectiveness of the lid. Once the pressure has been set it does not need to be
adjusted unless a different block or consumable is used.

1. Place the samples in the block and place the
lid in the down position.
2. Adjust the orange rotating knob
anticlockwise to give the least pressure then
close the lid fully.
3. Gently rotate the knob clockwise until you
can feel pressure beginning to be applied.
4. Rotate the knob a further quarter of a turn
and this will give the correct pressure.
