1. Safety instructions
The permanent magnets can generate consid-
erable forces of attraction and repulsion with the
result that there is a risk of squashing or splin-
tering.
• Be especially cautious when inserting mag-
nets into the basic unit.
• Never use the magnets except as specified.
Magnetic fields can erase data from magnetic
media and affect or destroy electronic or me-
chanical components like heart pacemakers.
• People with pacemakers should not conduct
this experiment.
2. Description
The NMR supplement set is to be used with the
ESR/NMR basic set (1000637 resp. 1000638) for
investigating nuclear spin resonance in glycerine,
polystyrene and Teflon.
The set consists of an NMR probe with a high-
frequency coil, a strong and uniform permanent
magnet, a glycerine sample, a polystyrene sam-
ple, a Teflon sample, an empty comparison sam-
ple and two discs for assembling the apparatus.
3. Technical data
Magnetic flux of
permanent magnets: 300 mT approx.
Frequency range:
11 − 15 MHz approx.
4. Maintenance and storage
• Remove any debris from the surfaces of the
permanent magnet poles and of the assem-
bly discs using a cloth with some isopropanol.
• Keep permanent magnets in a dry place.
5. Disposal
• The packaging should
be disposed of at local
recycling points.
• If the equipment itself
needs to be scrapped, it is
safe to dispose of all com-
ponents other than the
probe in domestic waste.
The probe should be disposed of in containers
dedicated to the disposal of electrical refuse.
