NOTICE
Material damage to the NMR probe or magnet from temperature control liquid.
Leakage of temperature control liquid from reaction control connectors into the NMR probe
or magnet may result in material damage.
u Use a temperature control unit with a maximum operating pressure set to <= 0.5 bar.
u Do not apply pressure greater than 1 bar to the reaction temperature line.
u Before introducing the flow unit 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 Use an inert, non-toxic temperature control liquid like glycol.
u The volume of the temperature control liquid must not exceed 5 liters.
CAUTION
Risk of contamination from toxic liquids or vapors after a glass flow tube
breakage or from flow unit leakage.
Contamination from toxic liquids or vapors may result after a glass flow tube breakage or
from leakage of sealing O-rings or connectors.
u Wear proper personal protective equipment. Examples include but are not limited to
gloves, goggles, lab coat, etc.
u For test purposes, use only non-toxic harmless compounds, for example sucrose in
H

O.
u Clean and decontaminate the entire flow unit assembly prior to service tasks and
confirm the decontamination.
NOTICE
Material damage to the reactor due to movement of the flow unit assembly.
Movement of the flow unit assembly during insertion/removal of the flow unit and InsightMR
transfer line into or from the magnet may cause damage to the reactor. Accidental
movement of the reaction transfer line by persons accessing the system may also cause
material damage.
u Secure the end of the InsightMR transfer line close to the reactor to prevent movement
(e.g. push/pull or rotation).
u Prevent access to the space between the reactor and magnet where the InsightMR
transfer line is installed.
