CryoProbe Installation BRUKER 71 (93)
Indium seals
There are two indium layers inside the CryoCooling Unit and two indium seals in-
side the CryoProbe.
Inside the CryoCooling Unit, open the big vacuum chamber. The Coldhead is
mounted inside of an arrangement of helical heat-exchanger pipes. There are in-
dium layers in the two contact faces between Coldhead and helix. Unlock the
screws and remove the indium.
At the CryoProbe, remove the semicircular bottom plate to gain access to another
large plate in the shape of a ring. Lift the plate. The two indium o-rings make the
seal between the ring-shaped plate and the body.
Indium must be recycled or disposed according to local regulations.
