9.6 Magnet Platform
For  smaller  magnet  systems,  ladders  and  small  platforms  are  most  commonly  used  to
facilitate sample insertion, cryogen fills, etc.
Ladders  for  platforms  must  be  constructed  of  wood  or  aluminum  to  keep  magnetic
interference down to a minimum.
If climbing a ladder is not a feasible option, a magnet platform may be required. These  are
typically built to facilitate sample insertion on the larger systems (600 MHz and up), however
smaller platforms can be used on smaller systems.
The  platform  must  be  constructed  of  wood  or  other  non-magnetic  material.  It  must
accommodate  the  magnet  and  provide  safe  access  for  sample  insertion  and  cryogen  fills.
Consult you Bruker office for further guidelines when using a magnet platform.

9.7 Helium Flex Lines
The purpose of the helium flex lines is to transport the helium gas from the compressor to the
cold head and back. The flex lines are isolated and are usually placed on the floor.
• The preferred route is to keep the helium flex lines at floor level. The lines exit the rotary
valve column close to the floor, and continue to the compressor. The minimum bending
radius of 50 cm must be respected.
• It is always important to route the lines such that tripping hazards and obstructions are
avoided, and to protect the physical integrity of the flex lines at all times.
