Sample Tube Installation
The equipment images in this topic may differ slightly from your equipment; however, the instructions are the same unless otherwise noted. |
- Remove the sample tube stopper, if used.
- Place the connector nut, ferrule, and O-ring onto the sample tube stem. The sample tube ferrule is tapered slightly on one end, however it may be installed with the tapered end in the up or down position.

If analyzing samples with a surface area of 1.0 m2 or less, use filler rods in the sample and balance tubes. See Analyze Samples with a Total Surface Area of 1.0m2 or Less . |
- Attach the sample tube to the analysis port. Ensure it is fully in the port. Secure it in place by screwing the connector nut into the analysis port. Hand tighten the connector nut.
- If the balance tube is not installed, attach it to the balance port following the above procedures. If a filler rod was used in the sample tube, one must be used in the balance tube.
It is not necessary to remove and replace the balance tube between analyses unless it has been contaminated or if using a different size sample tube. |
- Place the Dewar cover under the sample and balance tubes and slide upward until it is 7.5 cm (3 in.) from connector nuts.
