5. Remove the stopper from the sample tube and insert the gas delivery tube into the sample
tube.
6. Insert the stopper loosely into the sample tube. The stopper helps prevent cool moist air
and dust from entering the tube, but it must be inserted loosely to allow a path for the
escaping gas.
The end of the gas delivery tube may be hot enough to cause burns if it was stored in
a heating station instead of a cooling station. Handle the gas delivery tube carefully to
avoid burns.
It is not necessary to use a stopper with sample tubes having an inside diameter of
only 5 mm (0.2 in.).
