Work tube packages for inert, vacuum & hydrogen atmosphere

Each package comprises a work tube of the specified diameter with a pair of end seals and heat shields appropriate for the operating atmosphere.

A probe thermocouple is included in all work tube pages for furnaces up to 1200 °C, for connection to a separate display or recorder. Above 1200 °C one end seal will have a 10 mm thermocouple gland with blanking plug to suit a probe thermocouple which must be ordered separately.

The work tube material in the packages are:

  • IAP where the furnace maximum temperature is 1000 °C or 1200 °C
  • RCA where the furnace maximum temperature is between 1400 °C and 1800 °C
