A. Flexible tubing
B. Ferrule
C. Gas delivery tube
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. Wear the cotton gloves supplied in the
accessories kit and handle the gas delivery tube carefully to avoid burns.
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.
It is unnecessary to use a stopper with sample tubes having an inside diameter of only
5 mm (0.2 in.).
7. Using the appropriate heating station adapter, place the sample tube in a vacant heating
station.
