Unloading a sample
1. If there is a sample carrier in the loader chamber attached to the bayonet, remove it (the chamber needs to be
vented and the carrier removed).
2. Switch off the electron and ion beam accelerating voltage. Retract the GIS, Omniprobe, EasyLift or STEM
modules (if present) to a safe state (cannot be used in combination with loader).
3. Close the loader chamber lid. After the lid is properly closed the P button starts to shine.
4. Press the P button, the button stop to shine and the pumping cycle starts, the stage moves to the loading
position at the same time. When the vacuum in the loader chamber is correct the pump light starts to shine and
the
OK button lights up indicating operation can continue. The gate valve lever interlock is released.
5. Turn the Gate Valve knob lever from LOCK to UNLOCK position. Then carefully pull the knob bar fully out from
the first mark on the knob drum to the second mark. Turn the knob bar (counterclockwise) to the LOCK position.
6. Move the unloading rod from the Parking position into the chamber while still holding the rod bar. When
resistance is found turn the rod bar to the left (counterclockwise) to enter the bayonet. Push forward and turn
the rod to the right (clockwise) and the bayonet will engage with the Sample Carrier on the Stage Adapter close
to the end of the rod travel.
7. Withdraw the rod back to the far end of the rod guide and place in the Parking position. The rod, bayonet and
sample carrier are now out of the specimen chamber and sit in the Loader chamber.

over the opening. This can be seen through the lead glass lid, then turn the knob bar to the LOCK position to
secure the valve.
