CELL HANDLING
In order to facilitate introduction to, and removal from the furnace, Isotech can provide for each cell,
supplementary equipment largely comprising an Inconel basket with detachable handle.
To prevent the cell-surface becoming discoloured, it is recommended that, before using the cell, the basket
and insulation be placed in the furnace and the furnace be taken to above the cell working temperature for
at least 2 hours. This operation outgases the basket and insulation, which may smoke and discolour during
this first temperature excursion. The cell can then be inserted into the basket in readiness for use. If
removing the cell with a thermometer in its pocket (e.g. tin cell), extreme caution is necessary in applying
support by means of the diametrically-pivoted handle. The handle will need to be maintained in a non-
vertical plane while being used for removing and replacing the assembly.
CELL KIT
Basket, handles, discs of ceramic insulation, Inconel baffles and platinum foil discs if required.
Sketches show the recommended assembly of the cell basket (and insulation discs) in a furnace core.
