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.
