ESCRIPTIONS
The chamber furnaces covered by this manual all have some specialist feature as follows.
1.1 AAF models
The AAF Ashing Furnaces incorporate pre-heated chamber air flow. The chambers of the
AAF 11/3 and AAF 11/7 are ceramic muffles wound with resistance wire. The model AAF 11/18
has a chamber heated by wire spirals mounted in ceramic carriers, isolated from the working
chamber by side walls of silicon carbide.
Each AAF model is supplied with an Inconel tray complete with detached handle. The AAF 11/18
model has a double-decker tray arrangement.
1.2 OAF models
The OAF 11/1 is an older version of the AAF 11/7, being functionally similar but without the
more compact case of the AAF. The OAF 11/2 is a two-chamber model heated by slab elements
which form the chamber floors, also having air flow through the chamber.
1.3 GSM 11/7
This is a conventional muffle furnace, with a Silica chamber. This gives a cleaner environment
than a standard ceramic muffle.
1.4 VMF 10/6
The Volatile Matter Furnace is designed for compliance with ISO 562. It is heated by wire
elements embedded in light weight ceramic fibre, and incorporates calibration ports to allow
insertion of thermocouple probes from the back under the crucibles.
1.5 Switches and Lights
