Furnace

When performing BET analyses, the furnace must be removed to allow placement of a cold bath dewar around the sample.

  The equipment images in this document may differ slightly from your equipment, however the instructions are the same unless otherwise noted.

Furnace Removal

  1. Unplug the furnace power plug and the thermocouple cable from the analyzer.

  1. Open the latch, then open the furnace.
  If used recently, parts of the furnace may be hot. Use the cotton gloves provided with the analyzer to protect your hands.

  1. Gently lift the right side of the furnace until it is free from the support post.

  1. Lower the furnace, moving it away from the support post until it is free of the retaining knob.
  2. Close the furnace and secure the furnace latch. Place the furnace in a location where it will be protected from damage.

Furnace Installation

  1. Hold the open furnace next to the support post. Raise the furnace, moving it above the support post until the retaining knob is inserted in the hole in the top of the furnace.

  1. When the retaining socket on the bottom of the furnace is located above the support post, gently lower the furnace until it rests securely on the post.

  1. When ready to begin the experiment, close the furnace around the sample tube and secure the latch.
  2. Plug the thermocouple cable and the furnace power cable into the appropriate connectors on the analyzer. These connectors are located on the recessed front panel.
