A wide range of optional accessories include:
wall mounting brackets
'L' stand allowing vertical and horizontal operation
selection of worktubes including: impervious aluminous porcelain (IAP), mullite, recrystallised alumina (RCA), metallic (APM), sillimanite and silica.
spares kit
chart recorders
ceramic insulation plugs
radiation shields
calibration certificates
work tube seals for vacuum/controlled atmosphere applications
overtemperature protection
probe thermocouple for calibration and accurate measurement of workpiece temperature
separate control boxes
timeswitch
process timers
gas safety systems
gas flowmeters
gas safety systems
furnace tables with heat resistance surfaces

Some tube furnaces have an intregral ceramic worktube, others require one to be added to operate
All tube furnaces require an additional ceramic or inconel worktube to allow the use of a gas atmosphere
Various worktubes are available to suit different applications
Sillimanite - porous, good thermal shock resistance, maximum temperature 1500°C
Impervious aluminous porcelain (IAP) - impervious, maximum temperature 1400°C
Mullite - impervious and resistant to flux, sulphurous & carbonaceous atmospheres, maximum temperature 1500°C
Recrystallised alumina (RCA) - impervious and highly resistant to chemical attack (99.7% Al2o3), maximum temperature 1800°C
Advanced powder metallurgy (APM) - impervious FeCrAl alloy tube, not susceptible to thermal shock, but unsuitable for use inside (MTF & CTF) wire wound tube furnaces, maximum temperature 1300°C

These vital components must be fitted to all tube furnaces to prevent heat loss and ensure good uniformity
Various types are available for different applications
Ceramic insulating plugs
Type C for a non atmosphere application
Type D for an inert gas atmosphere application
Radiation shields
Type D metal discs for up to 1200°C high purity atmosphere or vacuum
Type D alumina discs for up to 1800°C high purity atmosphere or vacuum
