3.1.1 Connecting Vacuum Fitting to Quartz Tube

•

With quartz tube inside ceramic furnace, slide Ultra Torr nut, ferrule, and Kalrez O-ring
over the end of quartz tube. (1, 2, 3)

•

Gently slide quartz tube into Ultra Torr elbow. (4)

•

Align threads of elbow and nut, then tighten the nut FINGER TIGHT.

3.1.2 Leak Checking Furnace

•

Cap the outlet of the furnace to begin the leak check.

•

Set the pressure of inlet to 15 psig and open the flow meter to maximum value.

•

When the ball in the flow meter drops to the bottom of the flowmeter tube, a seal has
been established.

If the ball does not drop, a leak is present. Inspect and tighten all fittings, then repeat the
previous steps until a seal has been established.

CAUTION: Do not operate the reaction furnace if a leak is present.
