Safety Precautions
Most systems also include a personal computer, a sample puck kit, and a helium-transfer kit. You
can order other options to expand the capabilities of the base system, including a magnet and
either the Model 6700 Magnet Controller or the Model 3120 Magnet Power Supply. The PPMS
can be equipped with a 1-T, 7-T, 9-T, 14-T, or 16-T longitudinal magnet or a 7-T transverse
magnet.
With the exception of 14-T and 16-T longitudinal systems and 7-T transverse systems, PPMS
units can operate with one of three different types of dewars: the standard, nitrogen-jacketed, or
high-capacity nitrogen-jacketed dewar. Two nitrogen fill ports located on top of the nitrogenjacketed dewar distinguish it from the standard (non-nitrogen-jacketed) dewar. Figure 1-2
illustrates the nitrogen fill ports, and Figures 2-1–2-3 illustrate these three dewars. A liquidnitrogen transfer adapter is included with all nitrogen-jacketed dewars.
The probe is the component that is inserted into the dewar. If the system has a longitudinal
magnet, the magnet is attached to the probe, as illustrated in Figure 2-4. Any system with a
magnet also includes the Model 6700 Magnet Controller or the Model 3120 Magnet Power
Supply.
Please save the original packing crates for your system so that you can ship components back to
Quantum Design for installation of an option, upgrading, or repair.

Safety Precautions
WARNING!
The PPMS superconducting magnets produce extremely strong threedimensional magnetic fields that can be dangerous and the PPMS uses
cryogenic liquids for temperature control. Critical PPMS-related safety
precautions include those for using superconducting magnets, for using
cryogenic materials (liquids and gases), and for using electrical equipment, as
is reviewed below.
Above all, Quantum Design and its staff ask that you use standard safe laboratory procedures.
™ Use common sense.
™ Pay attention to the system’s state and your surroundings.
™ If the behavior of the system appears unusual, something might be wrong with it. If so, take
appropriate action.
™ Supervise inexperienced users and train them in general electrical safety procedures.
The PPMS has safety features to prevent accidents from causing injury or serious equipment
damage. If you use the equipment in a manner that is not specified by Quantum Design, the
protection afforded by the equipment could be impaired.
