NOTICE
Material damage to the NMR probe from sample liquid after a glass flow tube
breakage.
Sample liquid leaking into the NMR probe as a result of breakage of the glass flow tube may
result in material damage to the NMR probe.
u Do not apply pressure above 10 bar to the flow unit assembly.
u Before introducing the flow unit assembly in the magnet, check for leakages in the unit
at the flow rate and temperature value s that will be later used during the experiment.
u Handle the flow unit assembly with care when inserting it into the magnet.
u Use a sample delivery pump with a maximum operating pressure below the specified
pressure limit of the flow unit assembly or set the pressure limit of the pump not to
exceed the specified pressure limit.
u The maximum allowed flow rate for the flow unit and reaction sample line is 5 mL/min =
0.3 L/h.
NOTICE
Material damage to the NMR probe from sample liquid leaking from flow unit.
Sample liquid leaking into the NMR probe as a result of flow unit leakage may result in
material damage to the NMR probe.
u Do not apply pressure above 10 bar to the flow unit assembly.
u Before introducing the flow tube assembly in the magnet, check for leakages in the unit
at the flow rate and temperature values that will be later used during the experiment.
u Exchange the glass flow tube sealing O-rings regularly. If using solvents that are known
to be destructive to polymers (Kalrez) exchange the O-rings after each use.
u Do not exceed the maximum flow rate for the flow unit and reaction sample line of 5 mL/
min = 0.3 L/h.
NOTICE
Material damage to the magnet from sample liquid after a glass flow tube
breakage or from flow unit leakage.
Sample liquid leaking into the bore of the magnet as a result of a glass flow tube breakage or
from flow unit leakage may cause material damage to the magnet.
u The volume of sample liquid in the reactor should not exceed 2.5 liters.
u Exchange the glass flow tube sealing O-rings regularly. If using solvents that are known
to be destructive to polymers (Kalrez) exchange the O-rings after each use.
u Do not exceed the maximum flow rate for the glass flow tube and sample line of 5 mL/
min = 0.3 L/h.
