4 Safety
4.1 Intended Use
The Cryo Trap is used to cool down the area below the objective lens while the object chamber is
at vacuum. This decreases contamination by binding the volatile hydrocarbons.
The Cryo Trap is an option for the following ZEISS field emission scanning electron microscopes
(FESEM) with airlock:
§
GeminiSEM 300
§
GeminiSEM 450
§
GeminiSEM 500
Using the Cryo Trap for any other purpose is not allowed and could be hazardous.
4.2 Safety Information
This manual only shows the hazards which are specific to the Cryo Trap. However the Cryo Trap
must be used together with a ZEISS electron microscope. For the risks regarding the operation of
the ZEISS electron microscope please refer to the relevant instruction manual before starting to
work with the Cryo Trap.
WARNING
Burning hazard
Danger of burns or frostbites when liquid nitrogen gets in contact with the skin.
4
Wear proper protection equipment when handling the liquid nitrogen and Cryo Trap.
4
Do not touch the cooling rod and the cooling plate inside the chamber as long as the de-
war is not empty.
4
The dewar has to be in upright position. Never unscrew the dewar as long as liquid nitro-
gen is in it.
4
Use suitable tools when filling up the dewar.
4
The dewar must be empty and must have room temperature before exchanging the cool-
ing plate of the Cryo Trap.
WARNING
Explosion hazard
Explosion risk if the pressure inside the dewar rises due to evaporating liquid nitrogen.
4
Only use the cover which is provided by ZEISS for the dewar filling hole.
4
Regularly check that ice does not build up at or around the cover for the dewar filling hole.
WARNING
Suffocation hazard due to lack of oxygen
Danger of nitrogen accumulation in low-lying areas or subterranean rooms.
4
Ensure the room is ventilated properly.
